i think is 3/2. im no really sure
Answer:
$597.78
Step-by-step explanation:
$559.98 * 6.75% = 37.798 = 37.80
$559.98 + 37.80 =$597.78
The answer is: [A]: ∡PQT and ∡TQS ; since this pair of angle add up to exactly 90°, AND form a right angle (90° angle).

Answer:
x = 117.9°
Step-by-step explanation:
We require to find the size of the angle x
Given the law of cosines
c² = a² + b² - 2ab cosC
Rearrange to give cosC in terms of the sides
Add 2ab cosC to both sides
c² + 2ab cosC = a² + b² ( subtract c² from both sides )
2ab cosC = a² + b² - c² ( divide both sides by 2ab )
cosC =
here a = 55, b = 50 and c = 90 and C = x
cosx =
=
= ← - indicates angle is obtuse
x = ( ) ≈ 117.9°
