The answer is D because to use Pythagorean Theorem it has to be a right triangle.
Given:
m∠R = 90°
m∠Q = 6°
PQ = 2.2 ft
RP = x
To find:
The length of RP.
Solution:
Using basic trigonometric formula:
Multiply by 2.2 on both sides.
(nearest tenth)
The length of RP is 0.2 feet.
Answer: m<PQT=60 and m<PQS=4x+14
m<PQS and m<SQT are same
m<PQT = m<PQS + m<SQT = m<PQS + m<PQS = 2m<PQS
m<PQT = 2m<PQS
So m<PQS =
Plug in the given information and solve for x
4x + 14 =
4x + 14 = 30 (subtract 14 on both sides)
4x = 16 (Divide by 4 on both sides)
x = 4
The value of x is 4
2/5m + 7/5 you distribute and add like terms
The slope is 5/4
