The measure of an angle is 112.8°. What is the measure of its supplementary angle?


Im D u m b

Answers

Answer 1
Supplementary angels means that they both add up to 180°. So 112.8+x=180.
So subtract 112.8 from both sides and you get 67.2°. So the answer is 67.2°
Answer 2
If angles X and Y are supplementary
X+Y=90
x=16+3y
16+3y+y=90
4y=90-16
4y=74
y=74/4=18.50
x=90-18.50=71.50

Find JL.

PLEASE HELP IM STUCK :((K is the midpoint of JLIf:JK=9x-5KL=7x+3Find JL.

Answers

Answer:  62

Explanation:

K is the midpoint of segment JL

That means the smaller pieces JK and KL are the same length.

JK = KL

9x-5 = 7x+3

9x-7x = 3+5

2x = 8

x = 8/2

x = 4

This x value leads us to:

JK = 9x-5 = 9*4-5 = 36-5 = 31KL = 7x+3 = 7*4+3 = 28+3 = 31

Both smaller pieces are 31 units each, which helps confirm we have the correct x value.

Therefore, JL = JK+KL = 31+31 = 62

Area of five squares = 1289.09 square units

Perimeter =  194.6 units

Step-by-step explanation:

Area of square and perimeter:

   First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

                                  = 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

                                                         = 90 + 42 + 28 + 18.7 + 15.9

                                                          = 194.6 units

the area of the five squares is 1289.09 square units

the perimeter is 194.6 units

A right angle is shown divided in two parts. The measure of the angle of one part is 50 degrees and the measure of the other part is 5x plus 15 degrees.
a 5
b 7
c 11
d 15

Answers

Answer: a. 5

Since the angle is right, we know it is equal to 90 degrees.

Using the information provided, we can set up an equation.

50 + 5x + 15 = 90

Simplifying the equation, we get:

5x + 65 = 90

Subtracting 65 from both sides, we get:

5x = 25

Dividing both sides by 5, we get:

x = 5
