STEP 1:
Triangles= 180°

Other Angles= 7:13= 7x + 13x

Add all the angles to equal 180°

140° + 7x + 13x= 180°
combine like terms

140° + 20x= 180°
subtract 140 from both sides

20x= 40
divide both sides by 20

x= 2


STEP 2:
substitute x value to find other two angles

7x= 7(2)= 14° one angle

13x= 13(2)= 26° other angle


CHECK:
140° + 14° + 26°= 180°
140 + 40= 180
180= 180


ANSWER: The other two angles measure 14° and 26°.

Hope this helps! :)

Solve by completing the square<br>3x2 + x - 2 = 0​
DIA [1.3K]

Answer:

x = 2/3 or x = -1

Step-by-step explanation by completing the square:

Solve for x:

3 x^2 + x - 2 = 0

Divide both sides by 3:

x^2 + x/3 - 2/3 = 0

Add 2/3 to both sides:

x^2 + x/3 = 2/3

Add 1/36 to both sides:

x^2 + x/3 + 1/36 = 25/36

Write the left hand side as a square:

(x + 1/6)^2 = 25/36

Take the square root of both sides:

x + 1/6 = 5/6 or x + 1/6 = -5/6

Subtract 1/6 from both sides:

x = 2/3 or x + 1/6 = -5/6

Subtract 1/6 from both sides:

Answer:  x = 2/3 or x = -1

Answer:

  • D. 32 times; 5/4*40 = 32

Step-by-step explanation:

It is expected the spinner to land on Red 1/5 times.

<u>If the spinner is spun 40 times, then it should land on Red:</u>

  • 1/5*40 = 8 times

<u>And it should not land on red:</u>

  • (1 - 1/5)*40 = 4/5*40 = 32 times

Correct choice is D
