Answer:
the total of angle's in traingle is 180
so 85+53+c=180
c=180-138
c=42
It’s always gonna be 60 Units this is just an known fact
First find the difference in prices...
475 - 275 = 200 so the price went down 200 dollars. No we need to find what percentage of 475 is 200.
475 × x = 200
x = 200/475
x = .4211
Now convert to percentage by multiplying by 100 (move decimal 2 places to the right)
.4211 = 42.11%
It is a 42.11% price reduction.

Answer:</h2>
<u>By supplementary angle property</u>,
x + 78° = 180°
x = 180° - 78°
x = 102°.
