Answer:
12° and 168°
Step-by-step explanation:
If x is the angle, and y is the supplementary angle, then:
x + y = 180
x = y − 156
Solve the system of equations using substitution:
y − 156 + y = 180
2y = 336
y = 168
Plug back into either equation to find x:
x = 12
12 AND 168 DEGREES
Take supplementary angle as 180-X
Therefore: x={180-x}-156
x= 24-x
2x=24
x=12
Therefore one of the angle = 12 degrees
the other angle = 180-X degree
=180-12
=168 degrees
22cm and 16 1/2 cm is the answer
Write the ratio as a fraction and multiply with each dimension
2(2x + 5)
2 is common to both 4x and 10, so 4x + 10 = 2(2x + 5)

the answer is 4 it think it is correct
11. 8(12)+3(2.50)=103.5
12. 43
13. 10 pounds
