Answer:
112°
Step-by-step explanation:
Same-side angles of a trapezoid are supplementary.
m∠P = 180° - m∠S = 180° -68° = 112°
The angles of an isosceles trapezoid match their symmetrical counterparts.
m∠Q = m∠P
m∠Q = 112°
Well A seems like the most correct answer, the actual purpose of an afterburner is to inject fuel directly into the exhaust stream to increase thrust by as much as 50%. It’s usually used to go supersonic
Yes it can be. There are more than just right triangles but all right triangles are scalene
Answer:
x = 4
Step-by-step explanation:
3x÷2=6
Multiply both sides by 2.
3x = 12
Divide by 3.
x = 4
Frank can build a fence in twice the time it would take Sandy. Working together, they can build it in 7 hours. How long will it take each of them to do it alone?
Answer
If Frank and Sandy can build the fence in 7 hours, they must be building
1
7
of the fence every hour.
Now, let the amount of time it takes Sandy be
x
hours so that Frank takes
2
x
hours. Sandy can build
1
x
of the fence every hour and Frank can build
1
2
x
of the fence every hour.
We now have the following equation to solve.

Thus, Sandy takes

hours and Frank takes
21
hours.
