Let "a" represent the angle. Then its complement is (90-a). The complement is 39° more than the angle, so we have
(90-a) - a = 39
51 = 2a
25.5 = a
The measure of the angle is 25.5°; its complement is 64.5°.
Answer:
We cannot find a solution to the system of equations.
a+b = 5.30
2a + 2b = 14
Step-by-step explanation:
Let a = the price of an apple
let b = price of an orange
a+b = 5.30
2a + 2b = 14
Multiply the first equation by 2
2a+ 2b = 10.60
Subtract the second equation
2a+2b = 10.60
-2a+2b = 14
---------------------------
0 = -3.40
This is never true so there is no solution
