Complementary angles add up to 90 (there should be a right angle in the diagram)

x+20+x+10 needs to equal 90 where x=30

Left angle is measured 30+20=50 degrees

Angle on the right is measured 30+10=40 degrees

Simplify (we cannot solve if there is no equals)

6s^3(5s^2)(3s^4)

multiply the coefficients, add the exponents since the bases are the same

(6*5*3) s^(3+2+4)

90 s^(9)
