First distribute
5k + 20 - 2k
Then subtract (combine) the like terms
3k + 20
Answer:
61° , 151° , 12°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
∠ 1 + 29° + 90° = 180°
∠ 1 + 119° = 180° ( subtract 119° from both sides )
∠ 1 = 61°
-------------------
∠ 2 and 29° are adjacent angles on a straight line and sum to 180° , then
∠ 2 + 29° = 180° ( subtract 29° from both sides )
∠ 2 = 151°
----------------------
Using sum of angles in a triangle = 180°
∠ 3 + 17° + 151° = 180°
∠ 3 + 168° = 180° ( subtract 168° from both sides )
∠ 3 = 12°
