Answer:
x = 12.75
∠C = 51.75°
Step-by-step explanation:
The two marked angles are complementary, so ...
(5x -12) +(3x) = 90
8x = 102
x = 102/8
x = 12.75
__
C = (5x -12)° = (5(12.75) -12)°
∠C = 51.75°
__
<em>Check</em>
E = 3x = 38.25, then C+E = 51.75 +38.25 = 90 . . . . as it should
Answer:
The sale price is $1
$1 is not a better price since there is a cheaper price of $0.7
Step-by-step explanation:
Original price is $2
The price now is 0.5 × $2 = $1
If the sale price was 0.35 of the original price;
It would be 0.35 × $2 = $0.7
$1 is not a better price since there is a cheaper price of $0.7
