Help! What’s the measure of angle RST? Please explain, I want to learn.
KatRina [158]
The angle where the letter S is which would be angle RSQ = 1/2 x (131 +43) = 87

the angle opposite os RSQ would be PST and that would equal the same as RSQ which is 87

so 2 angles = 87 +87 = 174
 
so the other 2 angles need to equal 360 - 174 = 186

 since opposite angles equal each other divide that by 2 so 186 / 2 = 93

so both angle RST and PSQ are 93

The answer is D 93 degrees

adoni [48]
You would multiply 18 machines x 16" for a total of 288 inches. You would then divide by 36 because there are 36" (or 3 feet) in a yard. The answer is 8 yards of tubing.
