∠A = 24°
∠B = 87°
∠A = 24°
Explanation:
The sum of angles in a triangle is 180 degrees
let measure of angle A = ∠A
∠B = 15 more than three times the measure of angle A
∠B = 15 + 3∠A
∠C = 45° more than the measure of angle A
∠C = 45° + ∠A
∠A + ∠B + ∠C = 180° (sum of angles in a triangle)
∠A + 15 + 3∠A + 45° + ∠A = 180
collect like terms:
∠A + 3∠A + ∠A + 15 + 45 = 180
5∠A + 60 = 180
5∠A = 180 -60
5∠A = 120
∠A = 120/5
∠A = 24°
∠B = 15 + 3∠A = 15 + 3(24)
∠B = 87°
∠C = 45° + ∠A = 45° + 24°
∠C = 69°
Answer:
z=2
Step-by-step explanation:
60=-5(-6-3z)
60= 30+15z
60-30=15z
30/15=15z/15
2=z

Step-by-step explanation:
No
It is not proportional, because when x = 0, y does not equal 0.
when x = 0, y = -4. Therefore, it doesnt pass through the origin.
Answer:
Solve for x by simplifying both sides of the equation, then isolating the variable.
