The sum of the measures of the interior angles of a triangle add up to 180 degrees.
Since you have two angles of the triangle, add them up to equal 180 in an equation and solve for x (the third angle).
18 + 82 + x = 180
Combine like terms.
100 + x = 180
Subtract 100 from both sides.
x = 80
The third angle of the triangle is <u>80 degrees.</u>
Answer:
5 13/8 or 6 5/8
Step-by-step explanation:
2 3/4 + 3 7/8
since we are add we need to get a common denominator(bottom number)
I know that 2 × 4 = 8
3/4 × 2 = 6/8
new problem is
2 6/8 + 3 7/8
2+3=5
6/8 + 7/8 = 13/8
5 13/8
you may need to simplify you answer
13 - 8 = 5
6 5/8
