Yes, because they are similar(or you can call congruent), proved by SAS or simply HL.

For that to happen, they must be similar. Maybe you've heard of Thales theorem?

So, let's see how the ratio of vertical to horizontal is:

3/7 (in the first triangle)
9/21 (in the second triangle)

Is 3/7=9/21? Yup. So that it is the second one.

Answer:

Θ = 157.7°

Step-by-step explanation:

Given

cosΘ = - 0.925

Since cosΘ < 0 then Θ is in the second or third quadrant.

Since 0° ≤ Θ ≤ 180° then Θ is in the second quadrant. thus

Θ = $cos^{-1}$ (- 0.925) = 157.7° ← angle in second quadrant

Answer: 9

Step-by-step explanation:

Add 20, 12, and 32 together then divide by 7 because it says "One week" and a week is 7 days. So, it should be like 20 +12 + 32= 64

64 / (divided by) 7 = 9
