So, what you would have to do is figure out how old he is not which is 30 yrs old because it is half of 60.
So, after this you would have to find a number that would go into 60 four times which is 15.
So, your answer would be 15.
HOPES THIS HELPS!!!!
12a^-4 * b^-3
a= 2 and b = -1
Can you put 2 where it says a and -1 where it says b
Answer:
B is the best answer
The question is illustrated with the attached figure.
Required
Determine XY
To solve for XY, we make use of the tan function, which states that:
tan\theta = \frac{Opposite}{Hypotenuse}tanθ=
Hypotenuse
Opposite
In this case:
tan\ 60= \frac{YZ}{XY}tan 60=
XY
YZ
Substitute 4 for YZ
tan\ 60= \frac{4}{XY}tan 60=
XY
4
Make XY the subject
XY= \frac{4}{tan\ 60}XY=
tan 60
4
tan\ 60 =\sqrt 3tan 60=
3
So, the expression becomes:
XY = \frac{4}{\sqrt 3}XY=
3
4
Rationalize:
XY = \frac{4 * \sqrt 3}{\sqrt 3 * \sqrt 3}XY=
3

XY = \frac{4\sqrt 3}{3}XY=
3

Angle C is also 47 degrees since the two are congruent.
The sum of all the angles in a triangle is 180.
180 - 47 - 96 = 37
Your answer is the first choice.
Have an awesome day! :)
