Answer:
Y = 12 x = 13
Step-by-step explanation:
Triangular Sum says that the three angles in a triangle is 180˙.
So, <DAC + <ACD + <CDA = 180.
1. Substitute the angle measures into the equation above.
<DAC + <ACD + <CDA = 180
(3y + 2) + 52 + 90 = 180
3y + 144 = 180
- 144 -144
3y = 36
3 3
y = 12
m<DAC & m<CAB add up tp 90.
2. <DAC + <CAB = 90
38 + 4x = 90
- 38 . - 38
4x = 52
4 4
x = 13
