40°, 60° and 80°
sum the parts of the ratio 2 + 3 + 4 = 9
The sum of the angles in a triangle = 180°
Divide 180 by 9 to find one part of the ratio
= 20° ← 1 part of the ratio
2 parts = 2 × 20 = 40°
3 parts = 3 × 20 = 60°
4 parts = 4 × 20 = 80°
The angles in the triangle are 40°, 60° and 80°
Answer:
125 is 80% of 156.25
Working out percentages
We have, 80% × x = 125
or,
<u>80
</u>
100
x = 125
Multiplying both sides by 100 and dividing both sides by 80,
we have x = 125 ×
<u>100
</u>
80
x = 156.25
If you are using a calculator, simply enter 125×100÷80, which will give you the answer.

Answer:
the answer to your question is c
F(-3) = -2(-3)2 - 5(-3) +4
- 6 x 2 -15 + 4
- 12 -15 +4
- 27 + 4
-23
I believe this is how to solve the equation. I could be wrong.
