Answer:
AngleCAB = 44°
AngleHAB = 66°
Explanation:
AngleEAF is a right angle, equal to 90°.
EH and DC are just two intersecting lines. They form a couple of pairs of vertical angles. Vertical angles are equal to each other. We'll use the vertical angles, AngleEAD and CAH.
Angle EAD and CAH are equal to each other.
EAD = CAH
90°+20° = 2x + 3x
Combine like terms.
110° = 5x
Divide by 5
110/5 = x
22 = x
Angle CAB
= 2x
= 2(22)
= 44
AngleCAB = 44°
AngleHAB
= 3x
= 3(22)
= 66
AngleHAB = 66°
