The interior angles of a triangle are 60,45and 75.the shortest side is 10cm less than the longest side, determine the perimeter

masha68 [24]

Answer:

Step-by-step explanation:

We know that the permiter is defined as

$P=L+S+M$

Where $L$ is the longest side, $S$ is the smallest and $M$ is the middle side.

If $L=x$ then, $S=x-20$ , where we need to find an expression for $M$ using the law of cosines.

$M^{2} =L^{2}+S^{2}-2 \times L \times S \times cos(60\°)\\M=\sqrt{x^{2}+(x-20)^{2}-x(x-20)}\\M=\sqrt{x^{2} +x^{2}-40x+400-x^{2}+20x}=\sqrt{x^{2}-20x+400}$

Replacing all expression, the perimeter is

$P=x+x-20+\sqrt{x^{2}-20x+400}\\P=2x-20+\sqrt{x^{2}-20x+400}$

Using a calculator, the perimeter is 20 units centimeters.

The Moores family paid $6 more for skate rentals than the Cotters did. Together the two families paid $30 for skate rentals. How

Mademuasel [1]

<span>Moores Family Paid = 6 dollars mores for skate rental than the cotters did.
30 dollars = the total amount they paid for skate rentals.
Let Family Moore have the variable X
Let the Family Cotters have the variable Y
=> x = y + 6
=> y = 30 – 6 / 2
First, let’s solve the Y
=> Y – 30 – 6 / 2
=> Y = 24 / 2
=> y = 12
Now, let’s solve for X
=> X = y + 6
=> x = 12 + 6
=> X = 18

In the following figure, the value of x is____

zubka84 [21]

Answer:

x ≈ 8.3 ( to the nearest tenth )

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos41° = $\frac{adjacent}{hypotenuse}$ = $\frac{BC}{AB}$ = $\frac{x}{11}$
