Answer:
35
Step-by-step explanation:
Let number = x
(1/5 of x) + (3 * x) = 42 + (2 * x)
x/5 + 3x = 42 + 2x
1/5x + 3x - 2x = 42
1 1/5x = 42
6/5 x = 42
x = 42 ÷ 6/5
x = 42 * 5/6
x = 210 / 6
x = 35
The number is 35

<A = 62 and <ABE = 18
Sum of interior angles in a triangle = 180
So
<E + <A + <ABE = 180
<E + 62 + 18 = 180
<E + 80 = 180
<E = 100
Answer: first option
100
