The angle of elevation must be 68.202 degrees
Solution:
Given that, 14 foot ladder is used to scale a 13 foot wall
We have to find the angle of elevation must the ladder be situated in order to reach the top of the wall
The figure for this solution is attached below
The ladder, wall and the ground forms a right angled triangle
ABC is a right angled triangle
AB is the height of wall = 13 feet
AC is the length of ladder = 14 feet
We have to find the angle of elevation
Let the angle of elevation be "x"
For right angled triangle ABC, We can use the definition for sine
Here, in figure, opposite = AB and hypotenuse = AC
Thus the angle of elevation must be 68.202 degrees
The angle of elevation the ladder will be situated in order to reach the top of the wall is 68°.
A right triangle has one of its angles as 90 degrees. The angle of elevation can be found using trigonometric ratios.
Therefore, the angle of elevation can be calculated as follows;
The length of the ladder is the hypotenuse.
The opposite side is the height of the wall.
Therefore,
sin ∅ = opposite / hypotenuse
sin ∅ = 13 / 14
∅ = sin⁻¹ 0.92857142857
∅ = 68.2129901712
∅ = 68°

#SPJ5
(without tax) is $65.49.
If she is shopping in Pearland, where
the sales tax rate is 8.25%, what will
be the AMOUNT OF SALES TAX for
her dress (remember to round to two
decimal places since it's money)?
What’s the answer
Answer: Sales tax would be $5.40
Step-by-step explanation: The sales value itself of the dress (that is, without tax) is $65.49.
The amount charged as sales tax in Pearland is given as 8.25% (or 0.0825).
Hence if she is shopping in Pearland, the AMOUNT OF SALES TAX she would pay can be calculated as,
Sales tax = Sales price x 0.0825
Sales tax = 65.49 x 0.0825
Sales tax = 5.402925
Approximately to two decimal places, the sales tax becomes $5.40

Answer
Find out the how far has Rita hiked .
To prove
Let us assume that the rita hiked distance be x.
As given
rita is hiking along a trail that is 13.7 miles long.
she has hiked along of this trail.
Than the equation becomes
x = 1.37 miles
Therefore Rita hiked 1.37 miles of the a trail that is 13.7 miles long.
Answer:
Rita hiked 1.37 miles of the trail
