Answer:

3.5 °C

Step-by-step explanation:

To find the answer multiply 3 and 7 to get the sum of the temperatures in the first seven days.

3 x 7 = 21

Add 21 and 8 together to get the sum of the temperatures in the first 8 days.

21 + 8 =29

Divide 29 by 8 to get the mean temperature for the first eight days.

29 ÷ 8 = 3.5

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°
