In order for AB to be parallel to CD, the two labeled angles must be equivalent. If we set the two expressions equal to each other and solve for x, we can find the value of x that makes angle AEF and angle EFD equivalent and therefore the lines AB and CD parallel.

2x + 40 = 3x + 10
40 = x + 10
30 = x

If the value of x were 30, both angles would be 100°

Answer:

30°

30 is the value of x that’s makes AB//CD.

Step-by-step explanation:

the angles of measures 2x + 40 and 3x + 10 are two <u><em>Alternate interior angles </em></u>

If these two angle were congruent then the lines AB and CD

would be parallel .

2x + 40 = 3x + 10

⇔ 40 - 10 = 3x - 2x

⇔ 30 = x

⇔ x = 30

Fofino [41]
We know, length of arc = Ф/360 * 2πr
= 15/360 * (2 * 3.14 * 20)
= 1/24 * (125.6)
= 5.23

In short, Your Answer would be 5.23 Inches

What is the unit rate of 5/7 : 4/7?
allochka39001 [22]

9514 1404 393

Answer:

  a = 5/4

Step-by-step explanation:

To make the second number in this ratio be 1, you need to multiply the whole ratio by 7/4:

  (7/4)(5/7) : (7/4)(4/7) = 5/4 : 1 = a : 1

  a = 5/4

The circle passes through the point (−2, 3) with a center of (-4,6). What is its radius?
Ganezh [65]

Answer:

<u>radius = √13</u>

Step-by-step explanation:

Forming the equation :

<u>(x - h)² + (y - k)² = r²</u>

  • (x, y) = point on circle
  • (h, k) = center of circle
  • r = radius

Solving :

  • (-2 + 4)² + (3 - 6)² = r²
  • r² = 4 + 9
  • <u>radius = √13</u>

Simplify the expression. Write your answer as a power.
Gnesinka [82]

Answer:

(3/7)^7

Step-by-step explanation:

When multiplying exponents we can use the formula: a^m x a^n = a^m+n.

In this case, we can plug in 3/7 for a, and their respective exponents as m and n.

(3/7)^3 x (3/7)^4= (3/7)^3+4= (3/7)^7

Hope this helps!
