HELP!!! On a piece of paper, use a protractor to construct a triangle with angle measures of 30° and 50º. What is the measure of the third angle?

Answers

sum of all angles in a triangle must equal 180

so 

180 - (30 + 50)
= 180 - 80
= 100

answer:
third angle = 100

Remember that all of a triangle angles have to add up to 180 degrees. In that case, let's solve!: 30+50=80     180-80= 100

So the third angle is equal to 100. I hope this helped!!

Find the surface area of a rectangle prism

Answers

surface area
it is 6 rectangles
rectangle area=legnth times width

but yo have legnth width and height
how does we do this?
answer
recognize that the rectanles come in pairs
rectanels that are oposite each other have equal areas
so we have
top=bottom=legnth times width
front face=back face=legnth times height
R side face and L side face=width times height

since there are 2 of each
SA=2(LW)+2(LH)+2(WH)
undistribute 2
SA=2(LW+LH+WH)

tada
(note: L=legnth, W=width, H=height)


and give your answer in square units
