You can prove that the quadrilateral is a rectangle by finding out if the quadrilateral has opposite parallel sides, opposite congruent sides, and four 90 degree angles. You find out if the quadrilateral has opposite parallel sides by finding each sides slope(y2-y1)/(x2-x1). You find out if the quadrilateral has opposite congruent sides by finding each sides distance(distance formula=(y2-y1)squared+(x2-x1)squared, and that<------ is inside a radical. You find out if the quadrilateral has four 90 degree angles by seeing if each opposite sides slopes are reciprocals. Hope this helps, I'm typing this In the middle of doing A.P. history HW, so it might be kinda hard to understand.

Answer:

Horizontal distance between lifeguard and the person is 22 feet.

Step-by-step explanation:

Given: A lifeguard sees a person in distress.The eye level of the lifeguard is 15 feet above the ground. Angle of depression is 34°.

To find: Horizontal distance between lifeguard and the person.

Solution : If we draw a triangle then tan∅ = $\frac{height}{base}$

Here base is the horizontal distance.

Now we put the values in the formula.

tan 34° = $\frac{15}{base}$

Or Base = $\frac{15}{tan34}$

= $\frac{15}{0.675} = 22.22 feet$

So the answer is 22 feet.

ANSWER FAST NO LINKS 23=x-13 9+x=14 12=x+8

Anna35 [415]

Answer:

23=x-13, x=36

9+x=14, x=5

12=x+8, x=4

Step-by-step explanation:

23=x-13. You want to isolate x so you have to add 13 to both sides. x=23+13, x=36

9+x=14. You want to isolate x so you have to subtract 9 from both sides. x=14-9, x=5.

12=x+8. You want to isolate x so you have to subtract 8 from both sides. x=4.
