Step-by-step explanation:
the constant of proportionality is 3. thank me later : )
68°
ABD is a right angle and the measure of it is 90°
m<CBD + m<ABC = m<ABD
4x + 52° + 8x - 10 = 90° add like terms
12x + 42° = 90°
12x = 48°
x = 4
m<CBD is 4x + 52° replace x with 4
4×4 + 52 = 68°
x=10, y=6
the send equation minus the first.
(5x+y)-(3x+y)=56-36
2x=20--->x=10
then put x=10 to the first equation, 3*10+y=36, get y=6
