Answer:
90
Step-by-step explanation:
- change mixed number to improper fraction 22 1/2 = 22*2+1/2 = <u>45/2</u>
- now flip numbers on the second fraction 1/4 = 4/1
- now you can multiply across 45*4 and 18*2 = 180/2
- and simply so its 90
Answer:
Step-by-step explanation:
If you look at the large triangle, you will see that the side is opposite of 30° angle and the side 15 is opposite of 90° angle (<em>side opposite of 90° angle is called the hypotenuse</em>).
We have the angle, we have the side opposite and the hypotenuse. Which trigonometric ratio relates opposite side and hypotenuse? SINE!
<em>So we use the sin ratio and cross multiply and solve for :</em>
Hence,
I used math
anyway
remember you can do anything to an equation as long as you do it to both sides
so
4n+2 and 1/2=2n+5
minus 2n both sides
4n-2n+2 and 1/2=2n-2n+5
2n+2 and 1/2=0+5
2n+2 and 1/2=5
minus 2 and 1/2 both sides
2n=2 and 1/2
divide both sides by 2
I mean times both sides by 1/2
n=1 and 1/4
answer is C
Answer:
No.
Step-by-step explanation:
Because perpendicular means negative reciprocal of the slope. So 4 and -1/4 are perpendicular.
