Answer:
P = 62° Q = 28°
Step-by-step explanation:
Let x = measure of angle Q
then y = measure of angle P
Now x + y = 90 and 2x + 6 = y
Substituting 2x + 6 from the second equation in for y in the first equation, we get x + 2x + 6 = 90 since the two angles are complementary.
3x + 6 = 90
3x = 84
x = 28
y = 2(28) + 6 = 56 + 6 = 62
Check: 28 + 62 = 90
To solve this, let's first convert the equation to standard form:
9 + (x/4) = 12
Now, let's solve for x:
9 + (x/4) = 12
9 + (x/4) - 9 = 12 - 9
x/4 = 3
x/4 * 4 = 3 * 4
x = 12
