Let x be the angle. The complement is 3x + 10. The sum of two complementary angles is 90. So,
x + 3x + 10 = 90
4x + 10 = 90
4x = 80
x = 20
Plug x into the complement
3(20) + 10 = 70
The angle is 20 degrees and the complement is 70 degrees
The opposite side pairs in a rectangle are congruent, so basically QT would be congruent to RS when you draw the rectangle and label the points.
4x+10=30
4x=20
x=5
Answer:
a = 19
Step-by-step explanation:
Given the equation of:

First, multiply both sides by 3. That will clear the denominator which makes it easier to solve for a variable:

Subtract both sides by 5 to isolate the variable:

Therefore, the value of a is 19.
