b. B
c. D
d. E
e. C
Step-by-step explanation:
Linear pairs are supplementary, so ...
∠2 = 180° -∠1 = 180° -130° = 50° . . . (a)
∠6 = 180° -∠7 = 180° -70° = 110° . . . (d)
Vertical angles are congruent, so ...
∠5 = ∠7 = 70° . . . (c)
Exterior angles are equal to the sum of the opposite interior angles, so ...
∠4 = ∠2 +∠5 = 50° +70° = 120° . . . (e)
__
∠1 = ∠3 +∠5
130° = ∠3 +70°
∠3 = 130° -70° = 60° . . . (b)
SSS because they share the middle segment so it makes it similar

Answer:
180 people ran on the treadmill at the gym last week.
See the attached diagram.
In the right triangle, x is opposite the 23.6 degree angle, and the adjacent side is 250 m. This suggests using the tangent ratio.

Finally, to get the height of the tree, add Sarah's height, 1.5 m.
The tree is approximately 110.7m tall.
