This subject is pythagorean theorem

x = 170

Step-by-step explanation:

Formula: a² + b² = c²

a = side of right triangle  (known as the leg)

b = side of right triangle  (also known as the leg)

c = hypotenuse

So we will find the C (x).

a² + b² = c²

136² + 102² = c² (evaluate both 136 and 102.)

18,496 + 10,404 = c² (Add)

28,900 = c²

Now all we need to do is find the square root of 28,900.

√28,900 = √C²

170 · 170 = 28,900

So:

170 = C

x = 170

step-by-step explanation:

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
