<span>Are the lines in the diagram perpendicular, parallel, skew, or none of these?
l and m: neither
l and m intersect, but are not perpendicular.
l and n: skew
l and n are not parallel, but they do not intersect because they are not on the same plane.
m and n: perpendicular.
m and n intersect at a right angle</span>
Answer:
x=1
Step-by-step explanation:
3(4x+1)=15
12x+3=15
12x=15-3
12x=12
x=12/12
x=1
Your missing exponent would be 3
Answer:
Part A) ![sin(A)=\frac{2\sqrt{42}}{23}](https://tex.z-dn.net/?f=sin%28A%29%3D%5Cfrac%7B2%5Csqrt%7B42%7D%7D%7B23%7D)
Part B) ![cos(A)=\frac{19}{23}](https://tex.z-dn.net/?f=cos%28A%29%3D%5Cfrac%7B19%7D%7B23%7D)
Part C) ![tan(A)=\frac{2\sqrt{42}}{19}](https://tex.z-dn.net/?f=tan%28A%29%3D%5Cfrac%7B2%5Csqrt%7B42%7D%7D%7B19%7D)
Step-by-step explanation:
Part A) we know that
In the right triangle ABC of the figure the sine of angle A is equal to divide the opposite side angle A by the hypotenuse
so
![sin(A)=\frac{BC}{AB}](https://tex.z-dn.net/?f=sin%28A%29%3D%5Cfrac%7BBC%7D%7BAB%7D)
substitute the values
![sin(A)=\frac{2\sqrt{42}}{23}](https://tex.z-dn.net/?f=sin%28A%29%3D%5Cfrac%7B2%5Csqrt%7B42%7D%7D%7B23%7D)
Part B) we know that
In the right triangle ABC of the figure the cosine of angle A is equal to divide the adjacent side angle A by the hypotenuse
so
![cos(A)=\frac{AC}{AB}](https://tex.z-dn.net/?f=cos%28A%29%3D%5Cfrac%7BAC%7D%7BAB%7D)
substitute the values
![cos(A)=\frac{19}{23}](https://tex.z-dn.net/?f=cos%28A%29%3D%5Cfrac%7B19%7D%7B23%7D)
Part C) we know that
In the right triangle ABC of the figure the tangent of angle A is equal to divide the opposite side angle A by the adjacent side angle A
so
![tan(A)=\frac{BC}{AC}](https://tex.z-dn.net/?f=tan%28A%29%3D%5Cfrac%7BBC%7D%7BAC%7D)
substitute the values
![tan(A)=\frac{2\sqrt{42}}{19}](https://tex.z-dn.net/?f=tan%28A%29%3D%5Cfrac%7B2%5Csqrt%7B42%7D%7D%7B19%7D)
