In this case you would set it up as
6x + 4x + 130 = 180
(180 represents the degree of the triangle)

Add up like terms
10x + 130 = 180
Subtract 130 to the other side (180-130)

10x = 50
Divide 10 to the other side ( 50/10)
.
x = 5
Hope this was clear :)

The sum of the measures of the interior angles of a triangle is 180 degrees.

Make the three angles add up to 180 in an equation.

6x + 130 + 4x = 180

Combine like terms.

10x + 130 = 180

Subtract 130 from both sides.

10x = 50

Divide both sides by 10.

x = 5 is your answer.

The water level in a lake decreased by 2 1/4 inches in march and increased by 1 5/8 inches in april. Determine wether the water
mezya [45]

Change in level is given by :

C = increase in level - decrease in level.

Now,

Decrease in level in March is 2 1/4 = 9/4 inches.

Increase in level in April is 1 5/8 = 13/8 inches.

Putting value of these in above equation, we get :

C = 13/8 - 9/4

C = 13/8 - 18/8

C = -5/8 inches

Therefore, the overall level after April will decrease by 5/8 inches.

Hence, option 4. is correct.

Need help understanding and answering this please and thank you.
Goshia [24]

It's important to know that rigid transformations don't change the size or shape, this means the corresponding angles between the image and preimage are congruent. Due to the reflection transformation, angle C corresponds to angle Z.

<h2>Therefore, the answer is angle Z.</h2>

Answer:

<h3>Q 17</h3>

a is supplementary with 36 and b is supplementary with 113.

  • a = 180 - 36 = 144
  • b = 180 - 113 = 67

Correct choice is D

<h3>Q 2</h3>
  • LM = 1/2(AB + DC) = 1/2(46 + 125) = 85.5
<h3>Q 3</h3>

Diagonals of a rectangle are congruent

  • KM = LN
  • 6x + 16 = 49
  • 6x = 33
  • x = 33/6
  • x = 5.5

Correct choice is A
