Answer:
m∠A = 15°; m∠B = 89°; m∠C = 76°
Step-by-step explanation:
The sum of the three interior angles of a triangle is 180°.
Let x = m∠A
Then 3x + 44 = m∠B
and x + 61 = m∠C
x + 3x + 44 + x + 61 = 180
5x + 105 = 180
5x = 75
x = 15
m∠A = 15°
m∠B = 3(15) + 44 = 45 + 44 = 89°
m∠C = 15 + 61 = <u> 76°</u>
Sum = 180°
Answer:
y= -3x -3
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
c^2 = a^2 + b^2
c^2 = 8^2 + 6^2
c^2 = 64 + 36
c^2 = 100
c = 10
I added 8 on both sides to get 12=3x then I divided by 3 on both sides to get x=4
T= 21.79x + 3.99x + 6.89x where t is the total cost and x is the number of brushes/rollers/paint cans you buy. You don't need a different variable for each item because you buy the same amount of each.
