Answer:

Step-by-step explanation:
In order to find the value of ∠EFB here, we have to note our angle relationships.
We know that ∠CFE is already 90°. We also know that ∠CFA is 90°. Angle ∠AFB is inside ∠CFA. Since we know the measure of ∠AFB, we can find the measure of ∠BFC.

Now that we know ∠CFE and ∠BFC, which together make ∠BFE, we can add these angles up.

The complete proof statement and reason for the required proof is as follows:
Statement Reason
m<PNO = 45 Given
MO Given
<MNP and <PNO are a
linear pair of angles Definition of linear pairs of angles
<MNP and <PNO are
supplementary angles Linear Pair Postulate
m<MNP + m<PNO = 180° Definition of supplementary angles
m<MNP + 45° = 180° Substitution property of equality
m<MNP = 135° Subtraction property of equality
Answer:
Letter d :}
Step-by-step explanation:
Answer:
x=30°
y=30°
Step-by-step explanation:
x= 180-150=30°
y)
180=30 + 90 + z
z +120 = 180
z= 60
90-60=y
y=30
30°
(x - 9)/3 = 5/13
First multiply 3 to both sides to isolate the x
(x - 9)/3(3) = 5(3)/13
x - 9 = 15/13
Next, add 9 to both sides
x - 9 (+9) = 15/13 (+9)
x = 9 15/13
Simplify.
x = 10 2/13
Answer: x = 10 2/13
