Please Help! The following is an isosceles trapezoid, find m < J

ra1l [238]

Answer:

The measure of angle J is 44°

Step-by-step explanation:

Isosceles Trapezoid

The isosceles trapezoid has its non-parallel sides of the same length, thus the angles they form with their respective parallel sides are congruent.

It means: Angle J is congruent with angle K and angle M is congruent with angle L

The sum of angles in a trapezoid is 180*(4-2)=360°

Thus:

$m\angle J+m\angle K+m \angle M+m\angle L = 360^\circ$

$7x+2+7x+2+25x-14+25x-14=360$

Joining like terms:

$64x-24=360$

Adding 24:

$64x=384$

Dividing by 64:

x=6°

Thus:

$m\angle J = 7*6+2=44^\circ$

$m\angle M = 25*6-14=136^\circ$

The measure of angle J is 44°

Solve each equation by factoring 4) 4n? +n - 16=-2

Novosadov [1.4K]

Answer:

n=14/5

Step-by-step explanation:

4n+n-16=-2

We move all terms to the left:

4n+n-16-(-2)=0

We add all the numbers together, and all the variables

5n-14=0

We move all terms containing n to the left, all other terms to the right

5n=14

n=14/5
