Answer:
a=26°
Step-by-step explanation:
x+y=90°
(Because the third side is of 90° then by angle sum property of triangle the sum of other two side will be 90°)
x:y=3:2
Therefore, 3a+2a=90°
a=90/5
a=18
Then,
x=3a=54°
y=2a=36°
Since,y+z=100°
z=100-36
=64°
(y+z) + (x+a) =180°. (co-interior angles are supplementary)
100 + 54 + a = 180°
154 + a=180
a=180-154
=26°
