Answers

Answer 1

Answer:

The measure of angle D is of 66º.

Step-by-step explanation:

Vertical Angles:

If two angles are vertical, they have the same measure.

In this question:

Angles C and D are vertical.

Angle C measures 66º.

So the measure of angle D is of 66º.

co-terminal angle for -960... can you tell me?  :D  w/o looking at my answer below?

Your answer for co-terminal angle is   ______________ :)

960 - 360 = 600

600 - 360 = 240

this is telling us that going in a clock wise direction.. as the -960 is, that the co-terminal angle is 240, which seems about right.. looking at the graph. so now. let's take 240 away from 360 to find that co-terminal angle but going in the positive direction or the counter clock wise direction

360-240 = 120

and yes.. that does look like 120 °  going in the positive direction.  

now do you know the sec identity  to use sin and cos???

look at the below diagram

sin     sec

cos    csc

tan    cot

the trig function line up like that for a reason

sin     1/sin

cos    1/cos

sin/cos   cos/sin

I put them in their sin and cos identities.. see.. they all line up that way

sec = 1/sin

csc = 1/cos

tan = sin/cos

cot = cos/sin

now... find

sec(120) = 1/sin(120)

do you know how to find sin(120) ?????

put it back to it's co-terminal angle in the 1st quadrat... I hope you know how to do this.. i'll just speed along... assuming you do

sin(120) = sin(60)= √3/2

so sec(120) = 1 / √3/2  

so sec(120) = 2/ √3

10)

csc(315) = 1/cos(315)

find the co-terminal angle that you know in the 1st quadrant again...

so 315 = 45 in the 1st quadrant.. I just looked and can see that

so

csc(315) = 1/cos(315   =  1/cos(45)     and cos(45) = √2/2

so then  1 /  √2/2   =   2 / √2

csc(315) = 2 / √2

what i'm really wondering about.. is .. where is question 9)

There are 60 calico cats at the animal shelter if this represents 30% of the cats in the shelter how many total cats are there

Answers

Answer: 200 cats in total

Step-by-step explanation:

60 calico cats represents 30% of the total cat population in the shelter.

That means that if we find 30% of the total number of cats, the number we will get is 60.

Assuming the total is x, representing this in equation form makes it:

x * 30% = 60

x = 60 / 30%

x = 200 cats in total

Manoj went to the shopping mall and saw the price list in the shoe store as mentioned below in

Rs. 1000. He was returned 5 notes in denominations of Rs. 500 and Rs. 100. How many notes of
Rs. 500 and Rs. 100 did he get? Find out.
Type of Pair of Shoes
Price List
Casual Shoes
Rs.1,300
Formal Shoes
Rs. 1,800
Sports Shoes
Rs. 1,400​

Answers

Answer:

A Rs. 500 note, and four Rs. 100 notes.

Step-by-step explanation:

The cost of the two shoes = Rs.1,300 + Rs. 1,800

                                            = Rs. 3,100

He gave 4 notes of Rs. 1,000 = 4 x Rs. 1,000

                                                 = Rs. 4,000

Manoj's expected change = Rs. 4,000 - Rs. 3,100

                                           = Rs. 900

Since he was returned 5 notes in the denominations of Rs. 500 and Rs. 100, then;

Rs. 500 + Rs. 100 + Rs. 100 + Rs. 100 + Rs. 100 = Rs. 900

Therefore, Manaoj was returned a Rs. 500 note, and four Rs. 100 notes.

Solve for x (Geometry)

Answers

Answer:

x = 18[tex]\sqrt{2}[/tex]

Step-by-step explanation:

The middle line divides the 90° angle in half meaning your triangles are isosceles triangles. Recall that an isosceles triangle has sides that are the same length.

Using pythagorean theorem a² + b² = c², you can solve for x

18² + 18² = x²

x² = 648

x = 18[tex]\sqrt{2}[/tex]

So basically, You know you need a missing Base or height and you have the Area and The height or the base so in this case

A=Area

B=Base

H=Height

So, A divided by B-H gets B or H.

2= 5 base

3= 8 height

Problem: Jessica ordered a pizza. One-half of the pizza had pepperoni only, one-sixth of the pizza had mushrooms, and the rest of the pizza was cheese only. What fraction of the pizza was cheese only?

Answers

Answer:

1/3 of the pizza

Step-by-step explanation:

Number of pizza ordered = 1

pepperoni only part = One-half of the pizza = 1/2 of the pizza

Mushrooms part = one-sixth of the pizza = 1/6 of the pizza

Cheese only part = x

Total pizza = pepperoni only part + Mushrooms part + Cheese only part

1 = 1/2 + 1/6 + x

1 = (3+1) /6 + x

1 = 4/6 + x

1 - 4/6 = x

x = 1 - 2/3

= (3-2) / 3

x = 1/3 of the pizza

Cheese only part = x = 1/3 of the pizza
