Please help me Im really about to cry also can some help me with other questions

x = 25

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse x is equal to the sum of the squares on the other two sides, that is

x² = 20² + 15² = 400 + 225 = 625 ( take the square root of both sides )

x = = 25

25

Step-by-step explanation:

x= √20²+15²= √625= 25

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
