Question

Find the value of the variable What is x?

Answer 1

Answer:

x = 7

Step-by-step explanation:

I think there may be other ways to do this ... but this is one I  guess....

one angle= 90 ( given)

the other = 45 (given)

the third = 90 + 45 + a = 180  

(all angles of triangles is 180 [angle sum property])

                a = 180 - 135

                   = 45

The base angles are equal so that means it is a isoscles triangle. In isoscles triangle, two sides are equal ,  so

if one side is 7

the x is 7 too

(as it cant be the hypothenus)

I think this is right
