133  = 38 + m angle adjacent to n  (exterior angle of triangle theorem)
so m this angle =  133 - 38 = 95 degrees
Thus m  n = 180 - 95  = 68 degress

Its option A.

<span>An exterior angle of a triangle is equal to the sum of the opposite interior angles
</span>
so
n = (180 - 133) + (180 - 142)
n = 47 + 38
n = 85

answer is A. 85

What is the weight of one half of two thirds of a sack of rice? The sack of rice weighs 99 kilograms.
Eddi Din [679]
First you need to find what 2/3 equals
to do this, take 99 divided by 3
99/3=33

if 1/3 equals 33, two thirds would be 33x2
33x2=66

now, you need to find 1/2 of 66.  this can be done 2 different ways

1.    66 divided by 2    -    66/2=33
OR
2.    66 x 1/2 = 33     OR     66 x .5 = 33

The answer is 33 kilograms

5. What is the<br> complement of the<br> supplement of a 110° <br> angle?
Slav-nsk [51]
<h2>Answer:   20°</h2>

<h3>Step-by-step explanation:</h3>

Supplementary angles sum up to 180 °

Complementary angles sum up to 90°.

The supplement of 110° = 180° - 110° = 70°

The complement of 70° = 90° - 70° = 20°

<u>Simplier version:</u>

The complement of the supplement of 110° = (90° - (180° - 110°))

                                                                         = 20°

Rama09 [41]

change in y/change in x

y2-y1/x2-x1

-1--5/0-2

-1+5/-2

4/-2

-2

slope is -2

now take one ordered pair and plug it into the equation (for this example i will use the SECOND ordered pair

y = -2x +b

-1 = -2(0)+b

-1 = b

the equation is

<h2>y = -2x - 1</h2>
