Answer: X = 7

Step-by-step explanation:

3(2x - 5) = 55 - 4x

Open bracket

Collect like terms

6x + 4x = 55 + 15

10x = 70

x = 70/10

x = 7

Brainliest, what is the total measure of angles 8 and 5 of angle 7 equals 61
guapka [62]
Lines equal 180°. The line with angles 5 and 7 equals 180°. If angle 7 equals 61°, then angle 5 equals 119° (180° - 61°= 119°).

Angles 5 and 8 are opposite vertical angles, which are always congruent (equal), so angles 5 and 8 both equal 119°.

119° (angle 5) + 119° (angle 8)= 238°


ANSWER: The two angles total 238° (bottom choice).

Hope this helps! :)
