The answer is 525 / 28 =18.75
Answer: the answer is 224cm3
Answer:
Measure of angle R: Measure of angle S:
42 degrees <em><u>90 - 42 = 48</u></em>
30 degrees <em><u>90 - 60 = 30</u></em>
84 degrees <em> </em><em><u>90 - 84 = 6</u></em>
<em><u>Complimentary angles are angles whose sum is 90 degrees</u></em>
I'll do part (a) to get you started.
The angle 'a' pairs up with the 123 degree angle as a corresponding angle pair. Due to the parallel lines, the corresponding angles are congruent. Therefore a = 123.
We also see that b = 123 as well since a = b (they are vertical angles).
Notice how angle c is adjacent to the 123 degree angle. These two angles form a straight line, so they must add to 180 degrees.
c+123 = 180
c = 180-123
c = 57
-------------------------
To summarize, we have these three angles
a = 123
b = 123
c = 57
Hence thirty two dollars , is the solution
