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°
You need to write it in the form y = mx +b
since slope is m and b is the y-intercept, it would be written as y = -2x + -6

Answer:
The missing sides are 13 (small) and 2424 (big)
Step-by-step explanation:
The bigger triangle is bigger by 2 so multiply or divide the sides you do know by 2 to find the missing sides.
BC=12
ED= 12*2= 24
FD= 26
AC= 26/2= 13
Those usually mean the variable for the side length for a triangle.
