Step-by-step explanation:
all triangles add up to 180 so the equation is 2x+40=180
Answer:
r = 32 1/3
Step-by-step explanation:
5/(r-9) = 8/(r+5)
cross multiply:
5 x (r + 5) = 8 x ( r - 9)
5r + 25 = 8r - 72
Add 72 to both sides:
5r + 97 = 8r
Subtract 5r from both sides
97 = 3r
Divide both sides by 3
r = 32 1/3
