Amber has been working very hard and finally got a salary increase of 100%. She was earning $200 per week. How much is she earni

kogti [31]

Answer:

$400

Step-by-step explanation:

Given that:

Earnings per week for Amber = $200

Total increase in the salary as per Amber's hard work = 100%

To find:

Earnings of Amber now?

Solution:

We are given the initial salary and its percentage increase.

We have to find the increased value of salary.

Increase in the salary = 100% of $200

$\Rightarrow \dfrac{100}{100}\times \$200\\\Rightarrow \bold{\$200}$

Amber's Current salary = Initial salary + Increase in the salary

Putting the values of the initial salary and increase in the salary:

Amber's Current salary = $200 + $200 = <em>$400</em>

surveyor stands 100 m from the base of a tower on which an antenna stands. He measures the angles of elevation to the top and bo

balu736 [363]

Answer: 36.3m

Step-by-step explanation:

To solve this, we can draw two triangle rectangles, where the distance between the man and the base of the tower is one of the cathetus, the adjacent one, the height will be the opposite cathetus.

The triangle where the elevation angle is 58° is associated with the height of the tower without the aerial

The other triangle, where the elevation angle is 63° is associated with the height of the tower with the aerial.

Then we can calculate those two heights, then compute the difference, and the difference will be equal to the height of the aerial.

In both cases we want to calculate the opposite cathetus, then we should use the relation:

Tan(θ) = (Op. cath)/(Adj. cath)

The height without the aerial is h1, let's find it:

Tan(58°) = h1/100m

Tan(58°)*100m = h1 = 160m.

The height with the aerial is h2, let's find it:

Tan(63°) = h2/100m

Tan(63°)*100m = h2 = 196.3m

Then the height of the aerial will be:

h2 - h1 = 196.3m - 160m = 36.3m
