Answer: 101 Degrees for angle BCD

Step-by-step explanation: All 3 angles in any triangle add up to 180, in the first triangle (one on the left), you have 58 and 78 degrees, add them both and subtract from 180, you get 44 degrees for angle C on the left. Do the same on the right side of the triangle, you should get 35 degrees for angle C on the right. Add them both up, (35+44) then subtract from 180 degrees to find the measure of angle BCD.

Whats is 7 = 12v - 24?

Answers

Answer:

To the nearest tenth: v = 2.6

To the nearest hundredth: v = 2.58

Fraction form = 31/12

Step-by-step explanation:

1. Add 24 to both sides to cancel it out on the right

7 = 12v - 24

+24 +24

2. Divide each side by 12

31 = 12v

31/12 = 2.5833333

12/12 = 1v = v

v = 2.583333

It’s V=31/12

(1). 7=12v-24 (12v is a variable so you move it left hand side and change its sign)

(2). 7-12v=-24 (7 is a constant so move it to the right hand side and change its sign)

(3). -12v=-24-7 (now calculate the difference -24-7)

(4). Now it’s -12v=-31, now after that divide both sides of the equation by -12

(5). So the answer is V=31/12

The first angle in a quadrilateral is 150 degrees. The second angle in the quadrilateral is 30 degrees.
The other two angles are congruent.

What are the angle measurements, in degrees, of angle 3 and angle 4?

angle three is 30 degrees (depending on what kind of quadrilateral it is)

angle four is 150 degrees

Step-by-step explanation:

150+30

180 and if the other two are congruent meaning equal too

than they must also be 180 degrees in totale on the other side as well.

Angle is 30 degrees

Y=4x +5 y=x -4 a (3, 17) b (-3, -7) c (-3, 7) d (3, 7)

Answers

Answer:

(-3, -7)

Step-by-step explanation:

y = 4x + 5

y = x - 4

add 4 to both sides of the second equation to get y + 4 = x

plug that back into the equation to get y = 4(y + 4) +5

distribute to get y = 4y + 16 + 5

combine like terms y = 4y + 21

subtract 4y on both sides to get -3y = 21

divide both sides by -3 to get y = -7

plug -7 into the second equation to get -7 = x - 4

add 4 on both sides to get -3 = x

therefore (-3, -7)
