Find the values of X and Y.

Natasha_Volkova [10]

Answer:

x = 90°

y = 43°

Step-by-step explanation:

We know that one angle equals 47°.

The two triangles are right triangles, so that makes x = 90°.

To find y, we add 90 + 47.

That would give us 137°.

All triangles add up to 180°.

180 - 137 = 43.

43° is the answer.

A cab soup has a radius of 1.65 inches and a height of 4.4 inches how many cubic inches of soup does the can hold? Use 3.14 to a

yawa3891 [41]

Assuming that the cab soup is a cylinder, the volume = $\pi$ $r^{2}$ h
v= 3.14 * (1.65*1.65) * 4.4
1.65*1.65= 2.7225
2.7225 * 4.4 = 11.979
11.979 * 3.14= 37.61406 etc...
v rounded = 37.6

The cab soup can hold up to 37.6 $in^{3}$ of soup.
