Question

I need help in finding the the value of x to the nearest tenth?

Answer 1

Answer:

Step-by-step explanation:

13

Taking the side we can't quite see, I would guess it is an 8.

A 45 45 90 triangle is isosceles.

The two legs are equal.

x = 8

Little harder

The tangent of the angle is Tan(x) = opposite over adjacent

opposite = 10

adjacent = 15

Tan(x) = 10/15

Tan(x) = 2/3

x = tan-1(2/3)

x = tan-1(0.6666666667)

x = 33.7 degrees.

Do you know how to put this in your calculator.

gives

33.7 rounded
