The answer is D. 42
A triangle equals 180 in total so what you would do it subtract 122 from 180 because 180 is also the angle of a straight line. You would get 58 then you add 58 and 80 to get 138. Subtract 138 from 180 and you get your answer of 42
-DIVIDE- the area of a triangle by the -BASE-
, and -MULTIPLY- the result by -2-
Explanation:
Thats because the formula for the area of a triangle is 1/2 x base x height OR (much not confusing formula) BASE x HEIGHT divided by 2
Mark me brainliest tysm! Have a nice day
It's equal to 1.6x10^(-8)
I pretty sure it’s a linear function
