Answer:
a) <u>∡ADC = 270°</u>
b) <u>∠DAE = 38°</u>
Step-by-step explanation:
Using Inscribed Angle Theorem :
- ∡ADC = 2 x ∠ABC
- ∡ADC = 2 x 135°
- <u>∡ADC = 270°</u>
Similarly :
- ∠DAE = 1/2 x ∡DE
- ∠DAE = 1/2 x 76°
- <u>∠DAE = 38°</u>
(688-684) x 222
You have to do what’s in the parentheses first because of PEMDAS
688-684=4
Then you have to multiply
4x222
=888
-28 because if you add 8 to -120 you get -112 then divide it by 4 and you got -28
