Answer:
the length of RS to the nearest tenth of a foot is 240.6ft
Answer:
b = 12
Step-by-step explanation:
Complementary angles add to 90 degrees
a+b = 90
78+b = 90
Subtract 78 from each side
78-78+b = 90-78
b = 12
Answer:
875 + 61/2= 1811/2
1/2x + 31/2y= y + 31x/2xy
91/5x +91/5= 91 + 91x/5
Step-by-step explanation:
I did not understood the question but I hope thet was the Answer
Answer:
Step-by-step explanation:
Angle 5 is opposite to 37 => It's equal to 37.
Angle 6 and 7 are supplementary to angle 5 => They are equal to 180 - 37 = 143 each.
Angle 4 is corresponding to Angle 7, and since the 2 lines are parallel, it's equal to 143.
Angle 1 and 3 is supplementary to Angle 4, so they are equal to 180-143 = 37 each
Angle 2 is opposite to Angle 4, so it's equal to 143.
Answer : Angle 1,3,5 = 37
Angle 2,4,6,7 = 143
