The answer would be 77.7°
this can be proven because the two angles add up to 180°, therefore you just need to subtract the given angle from the sum

Answer:

77.7

Step-by-step explanation:

First all the angles add up to 360°. You would subtract 180 from the 360 because of the 2 right angles. That leaves you with 180. Then 180-102.3 to get 77.7°, your answer.

. If two polygons are similar how can you find the scale factor from one polygon to the other?
gayaneshka [121]

If two polygons are similar, then the ratio of a side-length of one of them
to the length of the corresponding side of the other one is the same number
for every pair of sides.  All you need to do is find one pair of corresponding
sides, then find the ratio of their lengths, and there's your scale factor.

Answer:

u = 12

Step-by-step explanation:

The equation is showing 5(u) = 60

<u>Begin: 5(u)= 60</u>

2. Divide the 5 from both sides to get the u-value alone.

a) 5u/5 = u b) 60/5 = 12

<u>Now: u = 12</u>
