Please help me to get correct answer

Mathematics
1 answer:
valentinak56 [21]3 years ago

Answer:

1. Because a right angle is 90 degrees, the answer to this is 90 - 65 = 25.

2. This question is similar to the last one, but this time the angle is 180 degrees total, so the answer is 180 - 55 = 125.

3. I'm fairly certain the lines here indicate that all three angles are the same. If all three angles make 180 degrees, the answer would be 180 / 3 = 60.

4. This is the same as in question 2. 180 - 135 = 45.

5. Again, because all three angles need to make up 180 degrees, we can just simply do 180 - (65 + 45) = 70.

6. With a quadrilateral, the angles add up to 360 degrees. We can do the same thing as in question 5 here. 360 - (70 + 95 + 55) = 140.

7. I don't remember exactly how to solve this but 55 degrees is correct because 55 + 55 + 70 = 180 which is the only possible value.

I haven't done this kind of stuff in a looooong time so I hope this suffices! :)

Solve for x
4      12
--- =  ---      4x=36  36/4=9  x=9 = PQ=9in
3       x
4      18
--- =  ---       4x=54    54/4=13.5  x=13.5 QR=13.5in
3       x
4      24
--- =  ---       4x=72     72/4=18  x=18   PR=18in
3       x

18+13.5+9 = 40.5
Therefore, the perimeter of ΔPQR = 40.5inches
