    word problem w/ supplement and complement TEST TOMORROW :(

    find the measurement of two complimentary angles if their measures are represented by (3x-10) and (7x+20)

    and

    find the measure of an angle if the measure of its supplement is 47 more than twice the angle.

    1) What is the degree sum of two complementary angles?

    2) Pick a variable for the measure of the angle. Write an expression for "twice the angle". Add "47" to this to create an expression for the supplement. Add the variable and the expression. Set equal to the degree sum of supplementary angles. Solve.

    Solve (3x - 10) + 7x + 20 = 90

    find the measure of an angle if the measure of its supplement is 47 more than twice the angle.

    Solve 180 - x = 2x + 47
