The interior angles of any triangle must add up to 180° in measure. Right angles have measure 90°, so the missing angles in both triangles here have measure 45°.
In a 45°-45°-90° triangle, the legs and hypotenuse occur in a ratio of 1 : √2. This means
(1) <em>x</em> = 48 √2
(2) 88 = √2 <em>x</em> → <em>x</em> = 88 / √2 = 44 √2
You could also set up trigonometric equations to solve for <em>x</em> in each case:
(1) cos(45°) = 48 / <em>x</em> → <em>x</em> = 48 / cos(45°) = 48 / (1 / √2) = 48 √2
(2) cos(45°) = <em>x</em> / 88 → <em>x</em> = 88 cos(45°) = 88 (1 / √2) = 44 √2
30 × 0.15 = 4.5
30 + 4.5 = 34.5

Answer:
0.75*C
Step-by-step explanation:
Original cost is 100%, 25%sale means that Bill payed only 75% of original cost.
Each number can be written as a decimal, as a fraction, or as a percent.
75%=0.75=3/4
salePrice = 0.75C
or salePrice = (3/4)*C
