Two negatives added or multiplied make a positive.
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:
254.47 to the nearest tenth is 254.5mm
Step-by-step explanation:
Hey! here's explanation:
A= π x r^2 (squared)
so A = π x 9mm^2
which gives you the answer of 254.47
TO THE NEAREST TENTH IS 254.5!
