Given:
In ΔNOP, n = 910 inches, o = 110 inches and p=820 inches.
To find:
The measure of ∠P to the nearest degree.
Solution:
According to the law of cosine:
Using law of cosine in triangle NOP, we get
Putting the given values, we get
Taking cos inverse on both sides, we get
Therefore, the measure of ∠P is 33°.
Answer:
D. (-2, -3) and (-2,3) are reflections of each other over the x-axis.
Step-by-step explanation:
The only difference between the points is that they have opposite y values.
When you reflect over the x axis, the y value becomes its opposite. This would change the -3 to 3 and the 3 to the -3.
On a graph it appears like you're flipping the point upside down.
Therefore, the points were reflected over the x axis.
Answer:
x=21
<EAF=52°
<EAL=104°
Step-by-step explanation:
Since it has a bisector, the two angles are equal.
2x+10=3x-11
10+11=3x-21
21=x
<EAF=2x+10 = 2(21)+10 = 42+10 = 52°
<EAL=52*2=104°
