Find the value of X from the right triangle please can anybody answer this

DIA [1.3K]

Answer:

Step-by-step explanation:

in the first triangle an angle is 60 degrees so it means that the triangle is half of a equilateral triangle.

in this case the base leg is half of the hypotenuse.

x = 8

in the second triangle we have an angle that is 45 degrees and this means that the triangle has two congruent legs

x = 10

Explain all of the steps needed to simplify the equation 8(x+2) = 4(2x+9) using the order of operations.

sineoko [7]

Answer:

First, use the distributive property and distribute 8 to the $(x,2)$ in the first part of the equation to get $8x + 16$ .

Next, also use the distributive property to distribute the 4 to the $(2x+9)$ in the second part of the equation to get $8x+36$ .

The simplified equation looks like this: $8x+16=8x+36$ .

This is proportion,
so general rule is $
 \frac{a}{b} = \frac{c}{d} , 
\\ \\ a = \frac{bc}{d} , 
\\ \\ x= \frac{3*5}{8} =1.875

A retailer purchased an electric bicycle for Rs. 35000 and sold at a profit of 16% to a customer. How much did the customer pay

motikmotik

Answer:

Rs. 45,150

Step-by-step explanation:

Given data

Cost =Rs. 35000

Profit=16%

VAT=13%

Let us find the profit to be added

=16/100*35000

=0.16*35000

=Rs. 5,600

Let us find the VAT to be added

=13/100*35000

=0.13*35000

=Rs. 4,550

Hence the cost of the bike is

=4,550+ 5,600+ 35000

=Rs. 45,150

From an upstairs window, I can see my neighbor’s fence. The angle of depression is 7 degrees. If my window is 15 ft off the grou

Tresset [83]

Answer:

1.84ft

Step-by-step explanation:

From the figure attached,

AB = Height of the window = 15ft

Let the distance between the base of the housr and the fence 'C' = xft

If the angle of depression = 7°

Then angle of elevation of the top of the fence from the house = 7°

Now from right triangle ABC,

tan7° = x/15

x = tan7°×15

x = 0.1227×15

x = 1.84ft

Therefore, distance of the house from the fence is 1.84ft
