Take your problem and do 3x=x+40 and subtract the x from 3x and it should equal 2x then take 2x=40 divide 2x from 40 and your answer is 20

the 2 angles are congruent so...

x+40=3x set the 2 equations equal to each other

40=2x subtract x from both sides

20=x divide by 2

x=20 is the final answer

Have a blessed day!

what is the missing side in a right triangle if one leg measures 5 cm and the longest side measures 13 cm

Alika [10]

Answer:

The missing side is 12 cm length

Step-by-step explanation:

1. Let's review the information given to us to solve the case correctly:

Length of the longest side= 13 cm

Length of one leg = 5 cm

2. Using the Pythagorean theorem for finding the length of the second leg, because this is a right triangle:

2nd leg² = Length of the longest side ² - Length of one leg²

2nd leg² = 13 ² - 5 ²

2nd leg² = 169 -25

2nd leg² = 144

2nd leg = √144

2nd leg = 12 cm

The missing side is 12 cm length

Solve the equation. Then check your solution

kondaur [170]

Answer:

Option B is correct i.e. 21

Step-by-step explanation:

In the question we're provided with an equation that is :

v/7 = 3

And we are asked to find the solution for the equation .

Solution : -

 $\longrightarrow \: \frac{v}{7} = 3$ 

Multiplying by 7 on both sides :

$\longrightarrow \: \frac{v}{ \cancel{7} }\times \cancel{7} = 3 \times 7$

On further calculations , we get :

$\longrightarrow \: \blue{\boxed{v = 21}}$

Therefore , solution for equation is 21 .That means option B is the correct answer.

Verifying :

We are verifying our answer by substituting value of v in the equation given in question :

$\longrightarrow \: \frac{v}{7} = 3$

Putting value of v :

$\longrightarrow \: \cancel{\frac{21}{7}} = 3$

By dividing 21 with 7 , we get :

$\longrightarrow \:3 = 3$

$\longrightarrow \: L.H.S=R.H.S$

$\longrightarrow \: Hence , \: Verified.$

Therefore , our answer is valid .

Answer: 272.9 cm^2

How to:

25 * 8 = 200

9 * 8.1 = 72.9

Add the areas of the two rectangles

200 + 72.9 = 272.9 cm^2
