C. 0.767

How do you find the cosine of a triangle?

the cosine of an angle in a right triangle equals the adjacent side divided by the hypotenuse: Also, cos A = sin B = b/c.

The cosine formula to find the side of the triangle is given by: c = √[a2 + b2 – 2ab cos C] Where a,b and c are the sides of the triangle.

Pythagoras Theorem is a generalization of the Law of Cosine.

The law of cosine can be applied in any triangle.

Solve for x and found your answer to the nearest tenth.

Answers

Answer:

11.1

Step-by-step explanation:

To find the side measurement we have to use trig, and the trig function Cosine, or cos. We use the because cosθ=[tex]\frac{adjecent}{hypotenuse}[/tex]. So cosθ=[tex]\frac{x}{15}[/tex], then to isolate x multiply both sides by 15. Now we have 15cos42=x, plugging this into the equation we get that x=11.1

Find a formula for an arithmetic sequence that begins 80, 83, 86, 89, ...​

Answers

[tex]a_{n}[/tex] = 3n + 77

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 80 and d = a₂ - a₁ = 83 - 80 = 3 , then

[tex]a_{n}[/tex] = 80 + 3(n - 1) = 80 + 3n - 3 = 3n + 77

Answers

Answer:

i) p = 4

ii) p = 8

iii) p = 12

Step-by-step explanation:

Here, we need to understand the initial relation

Mathematically, we have this as;

2.79 * p = c

So let us calculate the value of p for each value of c

i) 2.79p = 11.16

p = 11.16/2.79

p = 4

ii) 2.79p = 22.32

p = 22.32/2.79

p = 8

iii) 2.79p = 33.48

p = 33.48/2.79 = 12

1.15x = 3.40  Divide both sides by 1.15 and round to the nearest cent.

x = 2.96

Check:

Last year + 15% (.15)

2.96 + .15(2.96)

UVWX is a parallelogram. What is the measure of angle XUV?

Answers

Answer:

We need more info.

Step-by-step explanation:

Even though we need more information to solve this, I can explain how to. if you want me to solve it for you, comment on here and tell me if they gave you any angle measurements. Until then, I'll tell you how.

Look at the attached photo as you read to help you visualize this. Assuming your parallelogram looks roughly like the drawing, you can see that ∠U = ∠W, and ∠X = ∠V. We can determine that because - when working with parallelograms - the angle opposite of the other is always equal. For instance, if the drawing I made is accurate to the one you're looking at, then if ∠U was equal to let's say 120°, then that means that the exact opposite angle, ∠W, would also be equal to 120°.

Offer is still on the table though. If the question gave you any information about any of the degree measures, comment it and I'll solve the problem for you.

Answers

Answer:

A straight angle is the same as half the circle and is 180° whereas a right angle is a quarter of a circle and is 90°. You measure the size of an angle with a protractor. Or could be shown by an arc on the figure to indicate which angles that are congruent

C=180-102=78
d=180-92=88
a+140=2*102 => a=204-140=64
a+b=2d=176 => b=176-64=112

Mateo decide pedir un préstamo de 600 soles durante 2 años a un banco el cual le ofrece una tasa de interés anual de 16%calcula al interés simple y el monto total que pagará al término de 2 años

Answers

Answer:

192 and 792

Step-by-step explanation:

Given that

The principal is 600 soles

The Time period is 2 years

The Rate of interest is 16%

We need to find out the simple interest and the total amount paid at the end of 2 years

As we know that

SImple interest is

= Principal × rate of interest × time period

= 600 × 16% × 2

= 192

And, the amount is

= Principal + interest

= 600 + 192

= 792

The measure of minor arc JL is 60°.

Circle M is shown. Line segments M J and M L are radii. Tangents J K and L K intersect at point K outside of the circle. Arc J L is 60 degrees.

What is the measure of angle JKL?

Answers

Answer:

m∠JKL = 120°

Step-by-step explanation:

The measure of an angle formed by a two tangents drawn from a point outside the circle is the the difference of the intercepted arcs

minor arc JL = 60     major arc JL =  360 - 60 = 300

m∠JKL = 1/2(300 - 60) = 1/2(240) = 120
