The answer is 3.785, but rounding it to the nearest hundredth is 3.78 or 3.79, depending on rather they wanted you to take the 5 and round up or just leave it off.
The surface area formula is 4 x pi x r^2
69 is the measurement of angle 2
Answer:
Prime.
Step-by-step explanation:
2x^3 - 3x^2 + 2.
There are no factors of this expression. It is prime.
By definition of supplementary angles,
∠ABD + ∠BDE = 180
5x + 17x - 18 = 180
22x = 198
x = 9
∠ABD = 5(9) = 45°
∠BDE = 180 - 45 = 135°
