Two complementary is 90 degrees. So the answer is B.
I belive the answer is 28.
Answer:
(a.): m∠ ACB = 40°; (b.): m ∠CBA = 25°; (c.): m ∠CAB = 115°
Step-by-step explanation:
Because Lines AB and DE are parallel, we can use the angle relationships to find the angles.
(For context of the problem, we can label the 40° angle as ∠C and the 155° as ∠B)
(a.) Angles C and ACB are vertical angles, which means they're congruent. Thus m ∠ACB = 40°.
(b.) AB is a straight line and angles B and CBA are supplementary angles. This means their total sum is 180°. We need to subtract angle B from 180 to find m ∠CBA:
(c.) We know that the sum of all the angles is 180°. Thus, we can subtract the sum of angles CBA and CBA from 180 to find the m ∠CAB:
Answer:
x=4♢
Step-by-step explanation:
When you add the 4 you get 4 angles which counts as 4 ♢

To find the volume of a cylinder, you do Bh = V (Base * height = volume.)
The base of a cylinder is a circle, and we find the area of a circle by doing π
. Pi has a constant value (~3.14) and the radios ('r') is given as 2 feet.
Now that we have our equation and values, just plug everything in:
π *
* 17 = V
Solving it, we get:
π * 68 = V
68π = V
