Question

Instructions: find the marked angle in the triangle diagrams and explain how you figured it out.

Answer 1

Answer: 84 degrees

Step-by-step explanation:

this triangle is an isosceles triangle meaning two sides are of equal length ( the two sides in this case being the ones marked with the two lines // and // ) and that also means the triangle will have two equal angles (48 and 48) how do we know that? The triangle looks like this essentially: (see image below) where angle a = to angle b

a triangles angles added up always =180 degrees

Since we proved angle a is equal to angle b, we should be able to also subtract them from 180 to find angle c. 48+48=96

and simply subtract 96 from 180 to get 84 degrees.

therefore the angle is 84 degrees
