Complementary angles add to 90 degrees.
3x+5+2x-15=90
5x-10=90
5x=100
x=20 <=======
Plug in the value of x
3(20)+5
60+5
65= angle A <========
2(20)-15
40-15
25= angle B <========
Answer:
The equation — E = mc2 — means "energy equals mass times the speed of light squared." It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same thing.
