Answers
Well, a right angle is 90. Two 89 degree angles would make 178, but we need to reach 180. I don't know if thats possible with two acute angles. Two right angles would make 180, but not acute angles. Sorry I couldn't answer your question, but ask your teacher for help.

What is 45% of 432? and how?
Answers
1. We assume, that the number 432 is 100% - because it's the output value of the task. 2. We assume, that x is the value we are looking for. 3. If 432 is 100%, so we can write it down as 432=100%. 4. We know, that x is 45% of the output value, so we can write it down as x=45%. 5. Now we have two simple equations: 1) 432=100% 2) x=45% where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that: 432/x=100%/45% 6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 45% of 432
432/x=100/45 (432/x)*x=(100/45)*x - we multiply both sides of the equation by x 432=2.22222222222*x - we divide both sides of the equation by (2.22222222222) to get x 432/2.22222222222=x 194.4=x x=194.4
now we have: 45% of 432=194.4
answer is 194.4 he\she just explain it
