This is a 30,60,90° triangle where the hypotenuse is equal to 4 meters and the slant height is opposite the 60° angle

The ratios of the sides and their opposite angle for this type of triangle are:

1,30°, √3, 60°, and 2, 90° so the relationship we need is:

x/4=√3/2  multiply both sides by 4

x=2√3

Triangle abc is similar to triangle def solve for both unknown sides
Serhud [2]

Given:

Triangles ABC and DEF are similar triangles.

AB = 6 m, BC = 16 m, CA = 15 m, DE = x, EF = 32 m, FD = y

To find:

The values of unknown sides, i.e., x and y.

Solution:

We know that the corresponding parts of similar triangles are proportional and triangles ABC and DEF are similar triangles, so

\dfrac{AB}{DE}=\dfrac{BC}{EF}=\dfrac{CA}{FD}

\dfrac{6}{x}=\dfrac{16}{32}=\dfrac{15}{y}

\dfrac{6}{x}=\dfrac{1}{2}=\dfrac{15}{y}

Now,

\dfrac{6}{x}=\dfrac{1}{2}

6\times 2=1\times x

12=x

Similarly,

\dfrac{1}{2}=\dfrac{15}{y}

1\times y=15\times 2

y=30

Therefore, the measure of unknown sides are x = 12 m and y = 30 m.

Find the selling price<br> original price: $16.95<br> discount: 54%<br> tax: 4%
Marta_Voda [28]

Answer:

$8.11

Step-by-step explanation:

Original Price: $16.95

Discount: 54% Decimal Form: .54

Tax: 4% Decimal Form: .04

Let's start with the discount...

16.95 x .54 =9.153 Round = 9.15

16.95 - 9.15=7.80

Now, for the tax..

7.80 x .04=0.312 Round = 0.31

7.80 + 0.31=8.11

Hence. the Selling price is $8.11
