Given:

A figure of a triangle.

To find:

The value of x.

Solution:

In a triangle, angle bisectors intersect each other at a point which is know as incenter. This point is equidistance form the each side.

Using the above property, we get

$4x-2=6x-8$

$4x-6x=2-8$

$-2x=-6$

Divide both sides by -2.

$x=\dfrac{-6}{-2}$

$x=3$

Therefore, the value of x is 3.

Left side angle = 180-150-12 = 18 degrees

10 / sin 12 = c / sin 18

c = 10 * sin 18 / sin 12

c = 14.9 cm to nearest tenth

After paying 8.5% sales tax and leaving a 20% tip, Gwyn paid $57.29. What was the cost of the meal before tax and tip? Round you

olga nikolaevna [1]

Answer:$33.41

Step-by-step explanation:

I converted the percentages to decimals and subtracted them from 1.

(Btw x stands for the cost before tip and tax)

This was the equation I came up with based on what was given to me;

57.29 = (1-0.085)x + (1-0.2)x

57.29=0.915x + 0.8x

57.29=1.715x

Divide both sides by 1.715 and should get 33.40524781

Since we are rounding to the nearest cent, the answer would be $33.41

Using linear function concepts, it is found that:

a) The initial value is of 3 and the rate of change is of 20.

b) The rate of change means that for each hour, the cost increases by 3 Dhs, while the initial value means that a flat fee of 20 Dhs is paid.

<h3>What is a linear function?</h3>

A linear function is modeled by:

$y = mx + b$

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0, and also can be considered as the initial value.

In this problem, the function that gives the charge C for renting a bicycle for h hours is:

$C(h) = 3h + 20$

Item a:

Comparing to the standard function, we have that:

The initial value is of 3 and the rate of change is of 20.

Item b:

The rate of change means that for each hour, the cost increases by 3 Dhs, while the initial value means that a flat fee of 20 Dhs is paid.

A triangular prism has a Surface Area of 48.735 km2. The base of the prism is a triangle with a height of 3 and an unknown base.

xeze [42]

The surface area of the prism is equal to the summed up area of the faces of the triangular prism.

The bases of the prism would be triangles with an unknown base, b, and height of 3. The area of the base is calculated through the equation,
A = bh/2
where b is base and h is height. Substituting the values,
A = b(3)/2

Since there are two bases, the contribution of the triangles for the surface area is,
2A = 3b

Next we calculate for the area of the triangle sides with length equal to b (same as the base of the triangle).
Area = b(12 km)
There are 3 sides such that the total area becomes,
Area = 36b

Hence, the surface area is,
48.735 km² = 3b + (36b)

The value of b from the equation is 1.25 km

ANSWER: 1.25 km
