Answer:
Step-by-step explanation:
x - 9 = 17
x = 26
the answer is D
Answer:
A quadrilateral's interior angles have a sum of 360°.
Given that we have 85°, 100°, and 90°(the right angle), and an unknown angle.
We can add these angles plus the unknown angle to equal a total of 360°.
85 + 100 + 90 + x(our unknown missing angle) = 360
simplify
275 + x = 360
Isolate x by subtract 275 from both sides;
-275 -275
x = 85, ∠1 = 85°
We can also double check:-
85 + 100 + 90 + <u>85</u> = 360
360 = 360 which is correct.
Find the area of the top ( circle) then multiply by the height.
Area = pi x r^2
Area = pi x 7^2
Area = 49pi
Volume = 49pi x 15
Volume = 735pi cubic cm.
