Answer:
Step-by-step explanation
larger angle = 76+2x
smaller angle = x
supplementary angles add up to 180
∴(76+2x)+x=180
76+3x=180
3x= 180-76
3x = 104
x = 104/3
x = 34.7°(smaller angle)≈ 35
larger angle = 76+2(34.7)
=76+69.4
=145.4≈ 145
Answer:
y=(-1/2)x+7
Step-by-step explanation:
y=mx+b
find slope (m)-> (4-5)/(6-4)
find y-intercept (b)-> 4=(-1/2)6+b
m= -1/2
b= 7

Answer:
x=-8
Step-by-step explanation:
collect like terms
-5x=40
divide both sides of the equation by -5
so the answer would be x=-8
