Answer:
Step-by-step explanation:
x + 3y = 24.....multiply by -1
5x + 3y = 36
------------------
-x - 3y = -24 (result of multiplying by -1)
5x + 3y = 36
------------------add
4x = 12
x = 12/4
x = 3 <=======
x + 3y = 24
3 + 3y = 24
3y = 24 - 3
3y = 21
y = 21/3
y = 7 <========
Answer:
Step-by-step explanation:
if angles are complementary, that means they add up to 90º
if one is 65.3, then the other is just 90 - 65.3
<S = 90º - <R
<S = 90º - 65.3º
<S = 24.7º
