Answer:
The height of the equilateral triangle is 
Step-by-step explanation:
we know that
An equilateral triangle has three congruent sides, and three congruent angles that each measure 60 degrees
To find out the height of an equilateral triangle, apply the Pythagoras Theorem in the right triangle ABD
Remember that the height of an equilateral triangle bisects the base.
see the attached figure to better understand the problem
substitute the given values
Solve for BD
simplify
`
therefore
The height of the equilateral triangle is
The ratio of AB to AC and the ratio of AD to DC is 1 : 2 each respectively. They are equivalent ratios.
<h3>Ratios and proportions</h3><h3 />
A ratio means a comparison of two different quantities while proportion is an equality of two ratios.
- AB = 5 in
- AC = 10 in
- AD = 4 in
- DC = 8 in
Ratio of AB to AC = 5 in : 10 in
= 5 / 10
= 1 / 2
= 1 : 2
Ratio of AD to DC = 4 in : 8 in
= 4 / 8
= 1 / 2
= 1 : 2
Therefore, the ratio of AB to AC and the ratio of AD to DC is 1 : 2 each respectively. They are equivalent ratios.

Answer:
Im not sure ok
Step-by-step explanation:
Im trying to solve too
<u>Given</u><u> </u><u>:</u><u>-</u>
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>
- The input when output is 21 .
<u>Answer </u><u>:</u><u>-</u>
The given function is ,
Substitute f(x) = 21 ,
- 21 = 2x + 5
- 21 - 5 = 2x
- 16 = 2x
- 16/2=x
- x = 8
