First, you can notice that the angle of 130 degrees and the angle next to it make up a line. So, they should add up to 180 degrees. We do 180-130 to get 50. So that angle next to 130 is 50 degrees. The interior angles of a triangle should add up to 180 degrees so let’s do 180-50 to get 130. The angles are equal to each other so we can just do 130/2 and get 65 degrees. Lastly, y=65 degrees.

What are RQS and TQS?
yaroslaw [1]

Answer:

m∠RQS = 72°

m∠TQS = 83°

Step-by-step explanation:

m∠RQS +m ∠TQS = m∠RQT

The two angles combine to make a larger angle

So

m∠RQS = (4x - 20)

m∠TQS = (3x + 14)

(4x - 20) + (3x + 14) = 155

Group the Xs and the constants

4x + 3x - 20 + 14 = 155

Combine like terms

7x - 6 = 155

Add 6 to both sides

7x = 161

Divide by 7 on both sides

x = 23

Check:

4(23) - 20 + 3(23) + 14 = 155

92 - 20 + 69 + 14 = 155

155 = 155

But we need to find m∠RQS and m∠TQS. So plug in x = 23 to the values.

m∠RQS = 4(23) - 20 = 72°

m∠TQS = 3(23) + 14 = 83°

Checking:

72 + 83 = 155

Calculate the new area using a scale factor of 3.
Ludmilka [50]

Answer:

315

Step-by-step explanation:

Using a scale factor of 3 basically means just multiply the length and the width by 3.

So instead of 5 * 7, we are doing 15 * 21.

15 * 21 = 315

Solve for x in the equation 6(–5)=54 6 ( x – 5 ) = 54 .
Ad libitum [116K]

Answer:

x = 14

Step-by-step explanation:

Let's solve your equation step-by-step.

6(x − 5) = 54

Step 1: Simplify both sides of the equation.

6(x − 5) = 54

(6)(x) + (6)(−5) = 54(Distribute)

6x + − 30 = 54

6x − 30 = 54

Step 2: Add 30 to both sides.

6x − 30 + 30 = 54 + 30

6x = 84

Step 3: Divide both sides by 6.

6x/6 = 84/6

x = 14
