From the right triangle given, to obtain the unknown value we use the Trigonometry:
s/t
tan B=b/a
where:
B=15°
b=9
thus the value of a will be:
tan 15=9/a
solving for a we get:
a=9/tan 15
a=33.588~33.59

Answer:
1/4 miles.
Step-by-step explanation:
If I want to walk from my house to a clothing store 3/4 of a mile away, this implies that the location is 0.75 miles from my home.
Now, if after walking 1/2 mile I decide to stop, I will have traveled 0.5 miles in total. In this way, when I get back on my way, I will have to travel 0.25 miles to reach my destination (0.75 - 0.50).
Therefore, since 1 divided by 4 equals 0.25, I have to walk 1/4 mile to reach my destination.
Answer:
A
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
The angles are vertical angles which means they are equal
60 = 2x+20
Subtract 20 from each side
60-20 = 2x+20-20
40 =2x
Divide by 2
40/2 = 2x/2
20 =x
