Find the value of x that makes m ∥ n .
Alla [95]

Answer:

60

Step-by-step explanation:

(2x+15)=135    They're corresponding angles so they equal/congruent

<u>      -15   -15</u>       Subtract 15 on both sides since you're looking for x

<u>2x</u> = <u> 120</u>       Bring down the remains and subtract 135 from 15

 2        2        Add 2 on both sides

x= 60            Divide.

Find the value of x.
Rudiy27

Answer:

x=104

Step-by-step explanation:

Angle Formed by Two Secants= 1/2(difference of Intercepted Arcs)

10.5 = 1/2( x-83)

Multiply each side by 2

2* 10.5 = 2*1/2( x-83)

21 = x-83

Add 83 to each side

21+83 = x-83+83

104 =x
