Answer: 118
Explanation:
Since ∠A=∠ADB: ∠ADB=61°. The sum of the interior angles of any triangle is 180°, thus:
61°+61°= 122
180-122=58°
∠DBA=58°
Since triangle BCD is an equilateral triangle, all the interior angles are the same:
180/3=60
∠DBC=60°
∠BCD=60°
∠CDB=60°
Since angles DBC and DBA make up angle ABC, just simply add the two angles together:
58+60=118°
Therefore, ∠ABC is 118°.

Step-by-step explanation:
Answer: wouldn't be 1608.5? let me know if im wrong.
V = πr^2 h= π · 8^2 · 8 ≈ 1608.49544
-m
One times itself but as a negative.
Answer: 12.2474487139
Step-by-step explanation:
(I think what you wrote is just the square root of 150? if I read this wrong please let me know so I can correct my answer.)
*If you plug in the square root of 150 into a calculator, you get 12.2474487139
