Answer:
<h2>m∠1 = 100°, m∠2 = 80°</h2>Step-by-step explanation:
We know: Supplementary angles add up to 180°.
Therefore
m∠1 + m∠2 = 180° → m∠2 = 180° - m∠1 (*)
We have
Substitute (*):
<em>cross multiply</em>
<em>use the distributive property</em>
<em>add 5m∠1 to both sides</em>
<em>divide both sides by 9</em>
Answer:
time = 4.4 s
horizontal distance = 488.8 m
Step-by-step explanation:
Height, h = 4 ft
Angle, A = 32 degree above X axis
velocity, u = 131 ft/s
Let the time taken is t.
Use second equation of motion
So, time is 4.4 s.
The horizontal distance is
d = u cos A t
d = 131 cos 32 x 4.4 = 488.8 m
