Both of the missing angles are 45*.
Hope I helped. :)
The angles of a triangle all add up to 180º.
You need to set up and solve the equation:
84+48+3h = 180
3:8
Colored papers: white papers
White papers: 48
48/8= 6
3x6 = 18
There are 18 colored papers.
C is the answer. Congruent is just a synonym of similar therefore C is the answer.
17 because 100 - 55 = 45 14/45%= 31 31 times 55%= 17
