Answer:
m∠R = 39 degrees
Step-by-step explanation:
As complementary angles add up to 90 degrees, we can set up an equation to get x then find the measure of ∠R:
m∠R + m∠S = 90
2x+7+4x-13=90
6x+7-13=90
6x-6=90
6x=96
x=16
Since m∠R = (2x+7), 2x+7 would be 2(16)+7 or 39 degrees. So in conclusion, m∠R = 39 degrees
Answer:
1p = r
Step-by-step explanation:
You are asking how many 1-foot pieces you can make out of a 5 foot piece of ribbon. You are asking for an equation.
p = the # of pieces
r = the amount of ribbon
So lets try the equation:
1p = r
1(4) = r
1*4 = 4
4 = r
