On friday,
215 people went to the street fair. on
saturday, 163 more people went to the
street fair than on friday. on sunday,
192 people went. in total how many
people went to the fair? what are two
ways you can use to find the answer? ​

answer:

the answer to the first question is:

the triangle is an acute triangle.   because all of the sides are less than 90 degrees (acute). so, it's an acute triangle.

the answer to the second question is:

47 degrees.

all the sides of a triangle equal 180 degrees, so add what you have now, and subtract from 180 to find the last angle.

48 + 85 = 133

180 - 133 = 47

so, the answer is 47!     : )
