Answer:
132°
Step-by-step explanation:
∠AOB = ∠EOD = 3x ( vertical angles )
∠AOB + ∠BOC = 90, that is
3x + 0.5x + 34 = 90
3.5x + 34 = 90 ( subtract 34 from both sides )
3.5x = 56 ( divide both sides by 3.5 )
x = 16
∠AOE + ∠EOD = 180 ( straight angle )
∠AOE + 3x = 180
∠AOE + (3 × 16) = 180
∠AOE + 48 = 180 ( subtract 48 from both sides )
∠AOE = 132°
Answer:
see below
Step-by-step explanation:
The ASA congruence postulate is being invoked, so you're looking to show two angles and the side between them are congruent.
_____
Personally, I'd go at it differently. I'd say that alternate interior angles ∠C≅∠E means AE║CD, so ∠A≅∠D because they're alternate interior angles. B does not need to be a midpoint for this proof.
Answer:
t + 40 = 90
Step-by-step explanation:
90 minutes volunteering
40 minutes delivering flowers
90 - 40 = number of minutes answering phone (50 minutes)
so, t = 90 - 40 or rearranged to t + 40 = 90
