Answer:

64 degrees

Step-by-step explanation:

Since the triangles are similar they have the same angle measures

$\frac{PR}{PQ} =\frac{SU}{ST}$ $\frac{21}{14}= \frac{6}{4}$

∠P = ∠S ∠R =∠U ∠Q=∠T

We know 2 of the angle measures: ∠S and ∠R, and since they are similar we know ∠P and ∠U

In triangles the sum of all angle measures is always 180 degrees, so we can solve for ∠Q with this formula

$A+B+C=180$

$46+70+C+180$

$116+C=180$

subtract 116 from both sides

$C=64$

Therefore ∠Q is equal to 64 degrees

89 km would be about 55.3 miles! that's the best answer, but if they want you to round then I'd say choose 55 miles

FrozenT [24]

Johnny is selling tickets to a school play. On the first day of ticket sales he sold 14 senior (S) citizen tickets and 4 child (C) tickets for a total of $200. On the second day of ticket sales he sold 7 senior (S) citizen tickets and 1 child (C) ticket for a total of $92. What is the price of one child ticket?

14S + 4C = 200

14S = 200 - 4C

S = (200 - 4C)/14

7S + 1C = 92

7S = 92 - C

S = (92 - C)/7

(200 - 4C)/14 = (92 - C)/7

7 x (200 - 4C) = 14 x (92 - C)

1400 - 28C = 1288 - 14C

1400 - 1288 = 28C - 14C

112 = 14C

C = 112/14 = 8

the price of one child ticket = $8
