The answer is 135 because the angle equals 180 by itself and 180 subtracted from 45 is 135 .. I hope this is helpful
Answer:
a.) 5x
b.) 6xy
c.) 6xy
Step-by-step explanation:
5 * x = 5x
6 * x * y = 6xy
2 * x * 3 * y = 6xy
∵ ΔSRQ is a right triangle
and RT⊥SQ
∴ x² = ST * TQ
∴ x² = 9 *16 = 144
∴ x = √144 = 12
21/1 divided by 7/4 = 21/1 x 4/7 = 12.
Hope this helped my guy.
