Answer:
x=4
Step-by-step explanation:
We can find the length of RT by using the Pythagorean theorem
sin theta = opposite side/ hypotenuse
sin 60 = 2 sqrt(3)/ RT
Multiply each side by RT
RT sin 60 = 2 sqrt(3)
Divide by sin 60
RT = 2 sqrt(3)/ sin 60
RT = 4
Then
tan theta = opposite side/ adjacent side
tan 45 = x/RT
tan 45 = x/4
4 tan 45 = x
4 = x
Answer:
27
Step-by-step explanation:
643-166=477
477÷18=26.5
Then, round to the nearest whole.
Which makes it 27 sets.
Answer:
Angle 2
Step-by-step explanation:
<u><em>Vertical angles are congruent opposite angles when two lines intersect.
Line E A and B N intersect each other to form Angles B C A and E C N, or angle C and angle 2, which are congruent to each other as well, which makes them vertical to each other.</em></u>
