Angles A and B are supplementary. Angle A has a measure of 80 degrees. What is the measure of angle B?
Aleonysh [2.5K]
Supplementary angles, when added, equal 180 degrees

so < A + < B = 180...and if < A = 80
     80 + < B = 180
     < B = 180 - 80
    < B = 100 <==

100 points!!! i will award brainliest!! Lines AB, and CD are straight lines. Find x and y
Ket [755]

<O = 16 degrees   vertical angles are equal


<O + 4x+90 = 180   DC is a straight line

16 +4x +90 = 180

106 +4x = 180

4x =74

x =18.5


16 +90  +2y= 180   DC is a straight line

106+2y=180

2y = 74

y= 37

Answer : y=37

x=18.5

Evaluate -6(x-2y) when x= -3 and y= -5<br> a. -42<br> b. 80<br> c. -80<br> d. -16
Vinil7 [7]
Simply substitute x for -3 and y for -5, creating the equation shown below:
     
     -6 (-3 - 2(-5) )
Now that you have your values set up, now you can do the math by starting off with Multiplying -2 by -5, which will get you 10. 

Now that you have the parenthesis simplified in the parenthesis, you can use the distributive property by multiplying all the numbers with -6, like so:
-6(-3+10)= 18 - 60, which simplifies to -42, in which (A) is your answer.
