Natasha is measuring the angles of a triangle. she measures the first two angles and gets 60 degrees and 80 degrees. what should be the measure of the third angle?

a) 10 degrees
b) 20degrees
c) 40 degrees
d) 220 degrees

C) 40 degrees

Step-by-step explanation:

The total measure of a triangle is 180 degrees, therefore to find the other angle you would need to add the first two, and then subtract that sum from 180.

60 + 80 = 140.

180 - 140 = 40

Hope this helps!

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
