Answer:
use desmos.
Step-by-step explanation:
demos. All you have to do is out the equation into Desmos and it will graph it for you. You can look and learn.
(a) angle TPR = 90° - 30° = 60°
Reason: because the PTR is a right angled triangle.
(b) sin 30° = PR/14
PR = sin 30° × 14 = 7in.
(c) tan 30° = 7/TR
TR = 7/tan30° = 7 / (1/(#3))
= 7#3 in.
# : square root
(d) sin 45° = 7/PQ
PQ = 7/sin 45° = 7 / (1/(#2))
= 7#2 in.

Answer:
Step-by-step explanation:
She collected 2/6 gallon of orange juice from two trees and 2/3 from the last tree. To add these two fractions, both must have common denominators.
Multiply both the numerator and denominator of 2/3 by 2. This results in 4/6.
Now you have 4/6 + 2/6 which equals 8/6. This can be converted to 1 and 2/6, further simplified to 1 and 1/3. Therefore, Sue collected a total of 1 and 1/3 gallons of orange juice.
