What is an isosceles triangle?

A triangle with two sides equal is called an isosceles triangle.

Given that, an isosceles triangle, with base 6 units and legs 8 units, we need to find the length of the altitude x,

Since, ABC is an isosceles triangle, therefore, BD = DC = 6/2 = 3 units

Using the Pythagoras theorem,

AC² = DC² + AD²

8² = 3² + AD²

AD² = 64-9

AD² = 55

AD = √55

Hence, the value of x in the given isosceles triangle, is √55 units.

[tex]\sf{\implies \dfrac{N}{10} = 25}[/tex]

[tex]\sf{\implies N = 250}[/tex]

Now we need to find 60% of 250

First : He will meet his friend Tom at the skate park which is 15 minutes walk from his home.

So, James reached the skate park 10 : 15 AM

Second : They stayed at the skate park for an hour

So, till 11 : 15 AM James and Tom were at skate park

Third : Then they will take a 10 minutes walk over to the Burger bar

So, James and Tom reached the Burger bar at 11 : 25 AM

6) First let us find 75% of 80

[tex]\sf{\implies \dfrac{75}{100} \times 80}[/tex]

What is the length of leg s of the triangle below?
45°
90°
45°
10v2

Answers

Answer:

B

Step-by-step explanation:

The 45 45 90 triangle means that the hypotenuse is just one of the two legs multiplied by rad2. This means that leg s is 10.

The length of the leg is 10.

Option B is the correct answer.

What are trigonometric identities?

There are three commonly used trigonometric identities.

Sin x = Perpendicular / Hypotenuse

Cosec = Hypotenuse / Perpendicular

Cos x = Base / Hypotenuse

Sec x = Hypotenuse / Base

Tan x = Perpendicular / Base

Cot x = Base / Perpendicular

We have,

Sin 45 = Opposite face to angle 45/ Hypotenuse

1/√2 = s / 10√2

s = 10√2 / √2

s = 10

Thus,

The length of the leg is 10.
