meriva

Since (√36)² = (√18)²+(√18)², hence the triangle WXY is a right angle

<h3>What is Pythagoras theorem</h3>

The theorem states that the square of the hypotenuse is equal to the sum of the square of other two sides

For a triangle to be right angled, it must obey the law.

Given

Hypotenuse =√36

Other sides = √18 and √18

(√36)² = 36

(√18)²+(√18)²= 18 + 18

(√18)²+(√18)² = 36

Since (√36)² = (√18)²+(√18)², hence the triangle WXY is a right angle

F(2)=20(1.25)^x<br> STEP BY STEP
Nezavi [6.7K]
F(2) = 20(1.25)^x

f(2) = 20(1.25)^2 - plug in 2 to x

f(2) = 20(1.5625) - calculate 1.25^2

f(2) = 31.25 - simplify
