Answer:
55, 125 and 125
Step-by-step explanation:
In this question, we are asked to find the other 3 angles in an intersection.
Please check attachment for what the diagram of the intersection might look like.
The intersection consists simply of 4 angles meeting at a point with the 2 angles on each side vertically opposite to the angles on the other side.
since one of the angles is 55, and we are having a straight line, the other angle would be 180-55 = 125.[ sum of angles on a straight line is 180]
These two angles are vertically opposite, this means that the other three angles are 55,125 and 125.
1. 25% if 1/4, so we want to find 1/4 of 176. Best way to get the result is just divide 176 by 4, so 176:4=44 - its the answer.
2. To get the answer we can use proportion
100% -----------20
90% ---------- x
crossmultiply now
100x=90*20
100x=1800 /:100 divide both sides by 100
x=18 - its the answer
3. Similar problem
24 ---------- x
30 ---------- 100%
crossmultiply now
24*100%=30x
2400%=30x /:30 divide both sides by 30
2400%:30=x
80%=x - its the answer
Im not even sure about this though
Answer:
x= 120
Step-by-step explanation:
x+60=180
x=180-60
x=120
