Answer:
22.5°
Step-by-step explanation:
it's a right angle which equals 90°
which is 4 times as much as x
so i just divided 90 by 4
however since you are using formulas it would be written
90 ÷ 4 = x
The angle immediately below x makes up the third angle of the isosceles triangle whose base angles are 55°. That third angle and x are "vertical" angles, hence equal. The value of x can be found from the sum of angles of a triangle:
x + 55° + 55° = 180°
x = 70°
The appropriate choice is the 2nd one:
70°
