2. the sum of the measures of angle x and angle yis 90. if the measure of angle xis 30 less than twice the
measure of angle y, what is the measure of angle x?
o 20°
o 35°
50°
65°

50 degrees

Step-by-step explanation:

x + y = 90

x = 2y - 30

2y - 30 + y = 90

3y - 30 = 90

3y = 90 + 30

3y = 120

y = 120/3

y = 40

x = 2y - 30

x = 2(40) - 30

x = 80 - 30

x = 50 < angle x

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

it has to have an angle of 90 degrees
