Answer:
30°
Step-by-step explanation:
It tells us that MFE is equal to (x + 6)° so we need to find x
The angle accross from MFE is RFT. These angles are congruent, because they are a vertical pair. So RFT is also equal to (x + 6)°
The angle RFT and PFR combined form a right angle. This means that RFT + PFR = 90°.
They told us that PFR = (3x - 4)°
so that means that (x + 6) + (3x - 4) = 90°
Knowing that we can just solve the equation by combining like terms
4x + 2 = 90
Subtract two from both sides
4x = 88
And then divide by 4
x = 22
Now we can plug in 22 in the original equation to find MFE
22 + 6 = 30
so MFE = 30°
27 miles. Because in one hour he does 3 miles so in 9 hours he does 27
Answer:
1509
Step-by-step explanation:
We know that, formula for number of samples is,
When nothing is given, we take 
and we know that 
.
SE = 0.03 (the true proportion should remain withing 3%)
Putting the values we get,
Therefore, the sample required to estimate the true proportion to within 3 percentage points is 1509.
First, know which two sides are parallel. Then, go to the corners of the shorter side and draw a perpendicular line connecting to both sides
