t N.
In the figure shown below
Answer:
A horizontal line segment M K intersects with line segment J L at their midpoint N.
∠J N M =(5x+2)°
∠ LN M=3( x+ 14)°
So, ∠J N M + ∠ LN M =180°[ These two angles form linear pair.Angles forming linear pair are supplementary.]
⇒5 x+ 2+ 3 (x+ 14) =180 [ By Substitution]
⇒ 5 x+2 +3 x+42°= 180°
⇒ 8 x=180°-44°
⇒8 x= 136°
⇒x= 136°÷8
⇒x=17°
So, ∠J N M =5×17 +2=87°
∠ LN M= 3×(17 +14)=3×31=93
∠J N M =∠K N L [Vertically opposite angles]
∠K N L=87°
Answer:
The measure of
Step-by-step explanation:
According to the below diagram, horizontal line segment intersects with at their midpoint .
So, (As they are vertical angles)
Given that, and
As they are adjacent angles and points and are co-linear, so
That means.......
Thus,
Answer:
1/2 *b *h = (9*18)/2 = 81
Step-by-step explanation:
Area of a triangle is 1/2 * B * H
B is 18
H is 9
162 / 2 = 81
Answer:
81
Step-by-step explanation:
Formula: 1/2BH
B = length of base
H = height
1/2(18)(9) = 81
x+/5=12
x^2=16
3+x/7=3
7/x=14
Answer:
The second one
