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
Horizontal translation by h to the right (h>=0) is given by
g(x)=f(x-h)
For translation to the left, we have h=-3
g(x)=f(x-(h)) =f(x-(-3))=f(x+3)
Subtract three from both sides.
4x = 2x + 12 - 3
Simplify that
4x = 2x + 9
Subtract 2x from both sides
2x = 9
Simplify
x = 9/2 or 4.5
