Answer:

  • 142°

Step-by-step explanation:

<u>Since QS ║ MN, the following equations are true:</u>

  • m∠SQT = m∠QNM as alternate interior angles
  • m∠QNM = 180° - 72° = 108° as linear pair

The angle QSR is exterior of ΔSQT.

<u>Exterior angle measure is the sum of non-adjacent interior angles:</u>

  • m∠QSR = m∠SQT + m∠STQ
  • m∠QSR = 108° + 34° = 142°

PLEASE HELP ME 3X+1/14=2X/8 WHAT IS  X? EXPLAIN HOW YOU GOT THE ANSWER
balandron [24]
Cross-multiply so that 8(3x + 1) = 14(2x)

Distribute the 8 and 14 into the parentheses:
24x + 8 = 28x

Subtract 24x from both sides:
8 = 4x

Divide both sides by 4:
x = 2

-2 -13.8x = -8 -(6x+1)
Varvara68 [4.7K]
-2 -13.8x = -8 -6x -1
First, I distributed the negative 1 that was outside of the parentheses to the positive 6x and the positive 1.

-2 -13.8x = -9 -6x
Then I added the negative 8 to the negative 1 which equals negative 9.

-2 -13.8x +6x = -9 -6x +6x
After that I used the addition property and added a positive 6x to both sides.

-2 -7.8x = -9
Then simplifying.

+2 -2 -7.8x = -9 +2
After simplifying, I used the addition property again, adding a positive 2 to both sides.

-7.8x = -7
Simplified.

-7.8x (-1) = -7 (-1)
Then I multiplied both sides by with a negative 1 since the variable cannot be a negative.

7.8x = 7
Simplified

(1/7.8) 7.8x = (1/7.8) 7
Then, to isolate the veriable, I multiplied 1/7.8 to both sides.

x = 1.11428571429
The answer !

I hope this helped !

Answer:

12)

(9y +7)=(2y +98)( Because vertically opposite angle is always equal)

9y - 2y = 98-7

9y - 2y = 98-7

7y= 91

y =13

<em>ther</em><em>fore</em><em> </em><em>y</em><em> </em><em>=</em><em> </em><em>1</em><em>3</em>

<em>(</em><em>9</em><em>y</em><em> </em><em>+</em><em> </em><em>7</em><em>)</em>

9*13+7

117+7

124

(2y +98)

2*13+98

26+98

Convert 15/9 to a decimal. A. 1.64 B. 1.67 C. 1.66 D, 1.69
Travka [436]
15/9 = 1.6666... (where 6 repeats infinitely)

If we're rounding to 2 decimal places, 6 will round up to 7

Therefore, B. 1.67 is your answer
