Answer:
Note that the sum of the angles in a triangle are 180.
1. B. <R = 180 - 70 -55 = 55. Since <R = <T, then RS = ST
2. D. <J = 180 - 42 -96 = 42 = <K, so JL = KL = 12
3. B. Let the base angle = x. The vertex angle = 2x + 50. The sum of the angles in a triangle is 180, so x + x + 2x + 50 = 4x + 50 = 180 -> 4x = 130 -> x = 32.5.
4. D. Since <S = <Q, RQ = RS. Thus, 2x + 4 = 18 -> 2x = 14 -> x =7
I hope this helps!
The ratio 2 : 3 is the same as the ratio of 6 : 15. 2.) This is an example of scaling down by a scale factor of 5. The ratio 8 to 11 is the same as the ratio 40 : 55.
So X + 10 = 114
Isolate x by subtracting 10 from both sides
X = 104
Your number that is increased by 10 to get 114 is 104
I believe the GCF for the park 4 and 49 is 1.
