Question

answer the x side length of the triangle ​

Answer 1

By using h²=p²+b²(Pythagoras theorem )x²=4²+4²=16+16=32; x=(32)½=4(2)½, as the angles are 90°,45° and45° and the sides opposite to equal angles are equal. Please mark the answer as brainliest .

Answer 2

Answer:

mate

1st angle =45

2nd angle=90 (given)

3rd angle =?

• so,

by triangle rule,

angle 1st +angle 2nd + angle 3rd =180

45+90+3rd =180

135+ 3rd angle=180

3rd = 180 - 135

=. 55°
