To find the straight line distance from A to B, use the Pythagorean Theorem: AC2 + CB2 = AB2 ---> 412 + 342 = ab2
---> 2837 = AB2 ---> AB = 53.3
Walking from A to C to B = 41 + 34 = 75 meters.
Walking from A to B will save you 75 - 53.3 = 21.7 meters.
Since it is perimeter, it is just meters, instead of being squared or cubed like with area and volume.
12:16= 3:4 when simplified
12-9=3
16-9=5
When subtracting 9 from each the new ratio is 3:5
Hope this helps!
The answer to this question should be:
1. definition of supplementary angles
2. 115
3. definition of acute angle
Supplementary angles mean that the angle will add up to 180°. In this case, that means PQR + RQS= 180° where PQR=115°
So the RQS would be 180-115=65° Acute angle is when the angle is <90° so RQS is acute angles
