x=69

isosceles triangle are equal 69+69=138

180-138=42

180-42=138

138÷2=69

Step by step

Both triangles are isosceles.

For the right triangle:

69+69=138

180-138=42

For the right angle:

The 42 degrees meets at a right angle.

90-42=48

For the left triangle:

180-48=132

132÷2=66

x=66°

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
