Find the value of x that makes line m ll n

Mathematics
1 answer:
guapka [62]2 years ago
5 0

Answer:

See below ↓

Step-by-step explanation:

14.

  • Between two lines m ║ n, the ∦ cuts through them forming two angles
  • As it forms a line, the sum of the angles is 180°
  • 3x + 47 + x + 7 = 180
  • 4x + 54 = 180
  • 4x = 126
  • x = 126/4 = 63/2 = 31.5

15.

  • Alternate exterior angles on a transversal are equal
  • 5x = 2x + 78
  • 3x = 78
  • x = 26

Answer:

102

Step-by-step explanation:

Let the unknown measure be x

So all the angles add up to 180

therefore,

13 + 65 + x = 180

78 + x = 180

x = 180 - 78

x = 102

3 − m = −2 (m + 6); m = −15 Yes or No
Nimfa-mama [501]

Answer:

3 − m = −2 (m + 6); m = −15    Yes

5 (p + 3) = −35; p = −4            No

8q = 3 (10 + q); q = 6             Yes


Step-by-step explanation:

3 − m = −2 (m + 6)

3 - m = -2m - 12

m = -15

Answer is Yes


5 (p + 3) = −35

5p + 15 = -35

5p = - 50

p = -10

Answer is  No


8q = 3 (10 + q)

8q = 30 + 3q

5q = 30

q = 6

Answer is  Yes

Circle O has a circumference of approxim
aev [14]

Answer:

80 ft

Step-by-step explanation:

Circumference is approximately 250 ft

We want to find the diameter.

Circumference of a circle = π × D (D is the diameter)

So πD ≈ 250 ft

D ≈ \frac{250}{Pi} ≈ 79.57747155

Diameter is approximately 80 ft.
