Answer:
3.7feet
Step-by-step explanations
Using the sin rule
A/sin a = B/sin b
Let A = PQ = 8.5feet
B = QR = x feet
a = R = 90°
b = P = 26°
Substitute the values into the Sin rule
8.5/sin90 = x/sin26
8.5×sin 26 = x × sin 90
8.5×0.4383 = x× 1
3.7255 = x
Hence the length of QR to the nearest tenth 3.7feet
We know that
2 liters of pure water = 0 % of sugar
8 liters of syrup = 48% of sugar
Water = (2 liters x 0%) = 0 total sugar liters
Syrup = (8 liters x 48%) = 3.84 total sugar liters
Total liter mix =8+2-----> 10 liters
Total liters of sugar = 0 + 3.84 = 3.84
if 10 liters-----------> 100%
3.84 liters--------> x
X=3.84*100/10-----> x=38.4%
the answer is
38.4%
