Answer: ∠E=55°
Step-by-step explanation:
<u>Concept</u>
- In all similar triangles, their corresponding angle will be the same value
- Triangle angle sum theorem: the three interior angles of a triangle add up to 180°
<u>Given</u>
- Two pairs of corresponding angles
- Two similar triangles
<u>Solve</u>
(6x-15)+4x=(5x-1)+4x ⇔ Add the angles up
6x-15=5x-1 ⇔ Subtract 4x on both sides
x-15=-1 ⇔ Substract 5x on both sides
x=14 ⇔ Add 15 on both sides
180-4x-(5x-1) ⇔ Find ∠E by subtracting the other two angles from 180
=180-4(14)-([5(14)-1]
=180-56-69
=55°
Hope this helps!! :)

Answer:
y=60°
x=12°
Step-by-step explanation:
because the propertiy of parallelogram is the opposite side have equal measurement.
that is why y=60°
x+3=15 the paralla side are equal
x=15°-3°
x=12°
proof》》》》x+3=
12°+3°=15°
15°=15°
