The correct question is
<span>Suppose you know that S angle and Y angle are complementary, and that angle S=5(angle Y)- 180 degrees. What is the value of angle Y?
we know that
</span>S angle and Y angle are complementary
so
S+Y=90-------> S=90-Y------> equation 1
and
S=5Y-180----> equation 2
equate equation 1 and equation 2
90-Y=5Y-180------> 5Y+Y=180+90-----> 6Y=270-----> Y=45°
S=5*45-180-----> S=45°
the answer is
Y=45°
Hey there! I think the answer is -6r + 5
7(3r - 4)= 21r - 28 the answer to the question
then divide 448 by 2335 B + 10
