Answer:
Step-by-step explanation:
Ok so the question has already been answered by someone but i wanna give you some advice... it’s called ✨photomath✨ and you can take a picture of the problem or type it in... it would have been able to solve this equation right away, so you wouldn’t have had to wait for someone to answer. have a great day :)
m<1 = m<4 by vertical angles theorem
3x + 10 = 4x - 15
-1x = -25
x = 25
m<1 + m<7 = 180 if parallel alternate interior angles supplementary
3x + 10 + m<7 = 180
3(25) + 10 + m<7 = 180
75 + m<7 = 180
m<7 = 105°
Hope this helps! ;)
Answer:
A
Step-by-step explanation:
horizontal component=18cos 36.9°≈14.39 m/s≈14.4 m/s
Vertical component=18 sin 36.9°≈10.81 m/s≈10.8 m/s
