We can solve for x in by substituting 'y=15-5x' from the second one into the first equation, because in the second equation, y has no coefficient, which will make it easier to substitute.
Angle of depression=14°
height of tower=h=140 ft
tan(14°)=x/140
x=34.906 ft (distance from tent to the base of tower)
What is the question being asked here?
Step One
Find the complimentary angle of 28o Compliments add to 90o.
28 + c = 90
c = 90 - 28
c = 62o
Step two
Find the sin of 62o
sin(62) = 0.8829
So the answer is B
Another way to do it is to take the cos of 28
Cos(28) = 0.8829 which is still B.
Answer:
m∠2 = 113º
m∠3 = 67º
Step-by-step explanation:
m∠2 is supplementary to m∠1, meaning if you add them to m∠1, you will get 180º.
m∠2 + m∠1 = 180º.
m∠2 + 67º = 180º
m∠2 = 113º
m∠1 and m∠3 are vertical angles and are therefore the same.
