How do find the measure of similar triangle

1 answer:

6 0

If two objects have the same shape, they are called "similar." When two figures are similar, the ratios of the lengths of their corresponding sides are equal

Trigonometry question

Olegator [25]

Answer:

acute

Step-by-step explanation:

1. It cannot be right angle as the sides does not satisfy pythagoras theorem.

2. It cannot be obtuse angle as it does not satisfy the rule:

- the length of one side of a triangle must be greater than the differnce and less than the sum of the lengths of the other two sides.

Suppose the lengths of two sides of a right triangle are represented by 2x and 3 (x + 1), and the longest side is 17 units. Find

densk [106]

Answer:

x=4

Step-by-step explanation:

Step 1:-

given the lengths of two sides of a right angle are represented by 2x and 3(x+1) and longest side is 17 units.

AB = 2x and BC = 3(x+1) and longest side AC= 17

by using Pythagoras theorem

$AC^2 = AB^2 + BC^2$

step 2:-

The hypotenuse is longest side is AC = 17 units

(17)^2 = 4x^2 +9(X+1)^2

on simplification, we will use formula

$(a + b)^2 = a^2 +2ab+b^2$

289 = 4x^2 +9(x^2+2x+1)

$13x^2 +18x-280 = 0$

finding factors 70 X 52 = 3640

$13x^2 +70x-52x-280 = 0$

$13x^2 -52x+ 70x-280 = 0$

Taking common , we get

13x(x-4)+70(x-4)=0

x-4=0 and 13x+70=0

x=4 and $13x =-70$

x=4 and $x=\frac{-70}{13}$

we can not choose negative value so x value is 4

Final answer:- x = 4

verification:-

$AC^2 = AB^2 + BC^2$

289 = 4(4)^2+9(4+1)^2

289 = 64 +9(25)

289=289

Lanie is saving money to buy a car. She saved $772 so far. She earns $157 every month. How many months until Lanie has saved $2,

ser-zykov [4K]

Answer:

9 months until Lanie has saved $2,176.

Step-by-step explanation:

Given:

Lanie is saving money to buy a car. She saved $772 so far.

She earns $157 every month.

Now, to find the months until Lanie has saved until $2,176.

Let the number of months Lanie has saved be $x.$

She earns per month = $157.

She saved so far = $772.

According to question:

So, to get the months lanie has saved until $2,176 we write an equation.

$157x+772=2176$

Subtracting both sides by 772 we get:

$157x=1404$

Dividing both sides by 157 we get:

$x=8.95$

So, the number of months nearest to the month = 9.

Therefore, 9 months until Lanie has saved $2,176.
