Answer:
Step-by-step explanation:
According to the diagram we observe:
- ∠ACD is the exterior angle of triangle ABC.
As we know the exterior angle is same as the some of the remote interior angles.
It can be shown as:
Substitute the values and solve for x:
- 5x - 18 = 3x - 2 + x + 14
- 5x - 18 = 4x + 12
- 5x - 4x = 12 + 18
- x = 30
Find the measure of m∠ABC:
The matching <u>answer</u> choice is D.
Answer:
The Markup was by 25%
Step-by-step explanation:
The answer is 25% because 25% of 64 is 16
25% * 64 = 16

6.9 +3.9+7.9/2=54+27+31.5=112.5
From my knowledge, I know that cos(30) = ((2)^(1/2))/2, therefore 9cos(30) = 9((2)^(1/2))/2
I think it is 51.5, cause 412÷8 =51.5
