Answer:
<AEB = 51.2
Explanation:
Remark
A straight line has a degree value of 180. There are 3 angles. One of them is 90. The other two must add to 90
Equation
2.7x + 8 + 3.8x - 22 = 90 combine like terms on the left.
6.5x - 14 = 90 add 14 to both sides
6.5x = 90 + 14
6.5x = 104 Divide by 6.5
x = 104/6.5
x = 16
<AEB = 2.7*16 + 8
<AEB = 51.2
