Suppose BD bisects ABC. If m ABD = 12x+24 and m DBC = 20x +16 what is m ABC?
Answer:
The measure of ABC is 72
Step-by-step explanation:
if the angle ABC is bisected, it means that the two angles ABD and DBC are equal;
Thus;
12x + 24 = 20x + 16
20x -12x = 24-16
8x = 8
x = 1
The measure of angle ABC is the sum of the two angles
ABC = 12x + 24 + 20x + 16
ABC = 32x + 40
Substitute x = 1
ABC = 32(1) + 40
ABC = 72 degrees

19 points Solve for c. 5/4c+12=2
Answer:
C= -8
Step-by-step explanation:
I used a calculator
Answer:
c=-8
Step-by-step explanation:
[tex]\frac{5}{4}c[/tex] + 12 = 2
1.25c + 12 = 2 ( change 5/4 to a decimal for easy understading)
1.25c + 12 - 12 = 2 - 12 ( isolate the variable rememebr whatever you do to the right do it to the left )
1.25c = -10
1.25c / 1.25 = -10 / 1.25 (divide both sides by 1.25 )
c = -8
