Answer:
Which one?
Step-by-step explanation:
Answer:
<h2>D. 61</h2>
Step-by-step explanation:
Since ∠XAB and ∠VAW is a pair of vertical angles then they are congruent
then
m∠XAB = m∠VAW
then
2x + 16 = 138
then
2x = 122
then
x = 61
Answer:
the answer is B

The answer would be d, $15
Hope this helps!
Step-by-step explanation:
15 x 4/5=12
12+15=27
You can use the identity
cos(x)² +sin(x)² = 1
to find sin(x) from cos(x) or vice versa.
(1/4)² +sin(x)² = 1
sin(x)² = 1 - 1/16
sin(x) = ±(√15)/4
Then the tangent can be computed as the ratio of sine to cosine.
tan(x) = sin(x)/cos(x) = (±(√15)/4)/(1/4)
tan(x) = ±√15
There are two possible answers.
In the first quadrant:
sin(x) = (√15)/4
tan(x) = √15
In the fourth quadrant:
sin(x) = -(√15)/4
tan(x) = -√15
