Answer:
72°
Step-by-step explanation:
Let the 2 equal angles be x then the third angle is x + 18
The sum of the 3 angles in a triangle = 180°, thus
x + x + x + 18 = 180, that is
3x + 18 = 180 ( subtract 18 from both sides )
3x = 162 ( divide both sides by 3 )
x = 54
Hence
the largest angle = x + 18 = 54 + 18 = 72°
Answer:
47°
Step-by-step explanation:
angles x and 133 are supplementary, so they add up to 180°
subtract 133 from 180 to get 47
Answer:
x=2

Answer:
18.36
Step-by-step explanation:
Answer:
8/15
Step-by-step explanation:
Well to add fractions you have to have the same denominator so you would multiply your 1/3 by 5 to be 5/15 then you can add.
3/15 + 5/15 = 8/15
