Answer:

Step-by-step explanation:

Answer is sixteen. A squared plus B squared equals C squared.

A=15sq

B=6sq

C=Xsq

A=225

B=36

C=x

226 + 36 =261

261 = 16sq...roughly...

Answer is 16.

Hope this helps! I hope you do well on that test, we believe in you!

Given: A ABC The measure of measure of

shepuryov [24]

Answer:

∠A = 90

∠B = 30

∠C = 60

Step-by-step explanation:

Let ∠B = x

∠A = 3x

∠C = x + 30

Angle sum property of triangle: Sum of three angles of triangle is 180

x + 3x + x + 30 = 180 {Combine like terms}

5x + 30 = 180

5x = 180 - 30

5x = 150

x = 130/5

x = 30

∠A = 3*30 = 90

∠C = 30 + 30 = 60

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°
