What are the measures of the angles in the triangle? (6x + 10) (x + 17) (4x - 34)​
REY [17]

I'm not quite sure these are right. You might wanna check with a classmate or something first.

Step-by-step explanation:

(6x + 10) + (x + 17) + (4x - 34) = 180

11x - 7 = 180

11x = 173

x = 15.73 (answer had repeating decimal so i rounded up in the hundredths place)

(6x + 10)

6 (15.73) + 10

94.38 + 10

104.38

(x + 17)

(15.73) + 17

32.73

(4x - 34)

4(15.73) - 34

62.92 - 34

28.92
