Find the missing angle of a triangle if the first two values are 91* and 87 degrees

The missing angle has a measure of 2 degrees.

Step-by-step explanation:

Every triangle's inner angles can be added and will always equal 180. Therefore, use subtraction to find any missing angle. In this case,

180 - 91 = 89

89 - 87 = 2

So, your answer is 2.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
