∠A and ∠B are vertical angles. ∠B is supplementary to ∠C. If ∠C measures 42°, how large is ∠A?

Answers

Answer 1

Answer:

138 degrees

Step-by-step explanation:

Since angles B and C are supplementary, that would mean they add up to 180. The problem tells us that angle C is 42 degrees, so that would mean that angle B is 138 degrees. We are also told that angles A and B are vertical, which would mean that they are congruent to each other. That leaves us with the answer that angle A is 138 degrees.

Hope this helps! :)

Answer 2
I’m absolutely positive it’s 138 :) !!!

I need help now!!!!!!

Answers

Answer:

Step-by-step explanation:

Step 1: Multiply the whole number part (2) by the denominator (8).

2 × 8 = 16

Step 2: Add the product from Step 1 (16) to the numerator (1).

16 + 1 = 17

Step 3: Write that result (17) above the denominator. So,

2 1/8

Write an equation in point-slope form for the line that passes through each point.
(-2, 11), vertical line

Answers

Answer:

You can't make a point=slope form equation.

Step-by-step explanation:

The vertical line would be parallel to y- axis, hence its equation would be x= c . The slope of the vertical line is undefined, therefore there is no point slope form as such.

y-11=0(x+2)

y-11=0

y=11

Find the equation of the line that contains the points (-5, 0) and (-3, 4)

Answers

Answer:

y = -1/2x - 5/2

Step-by-step explanation:

With points (-5,0) and (-3,4), we need to find the slope first.

[Find slope of points]

Using slope formula m = (Y2 - Y1) / (X2 - X1)

Using points: m = (4 - 0) / (-3 - 5) = 4/-8 = -1/2

[Use point-slope formula]

(y-y0) = m(x-x0)

Using points: (y - 0) = -1/2(x - -5)

Finally: y = -1/2x -5/2

How is a chemical change different from a physical change?

Answers

Answer:

Step-by-step explanation:Physical changes only affect the physical properties, such as color, texture, and shape, of a substance. When a substance is changed physically, its chemical properties remain the same. On the other hand, a chemical change alters the chemical properties of a substance.During a physical change the elements and compounds stay as they are.While Chemical changes make new substances.

In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. The distinction between physical and chemical change is not clear cut
