Question

The sum of the measures of angle A and angle Y is 90. If the measure of angle X is 30 less than twice the measure of angle Y, what is the measure of angle X?

a) 20 degrees
b) 35 degrees
c) 50 degrees
d) 65 degrees

Is it d? Thank you!

Answer 1

I actually think it's c.

Answer 2

Establish equations
x+y = 90
x = 2y - 30
...
Substitute the x = into the first equation
2y - 30 + y = 90
...
solve for y
3y - 30 = 90
3y = 90 + 30
3y = 120
y = 40
...
Substitute y into either equation and solve for x
x = 2(40) - 30 = 80 - 30 = 50
...
Solution
x = 50, y = 40
(50,40)
