Step-by-step explanation:
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>
Answer 79.8
Step-by-step explanation:
Answer:
y = ± 12
Step-by-step explanation:
Given
y : 24 = 6 : y, or in fraction form
=
( cross- multiply )
y² = 144 ( take the square root of both sides )
y = ±
= ± 12
