given:
a | | b, c | | d
prove:
m1 = m16
*look at graphs attached*
which of the following would be the reasons for statements 3 and 4 in the proof?
a. vertical angles are equal.
b. if lines are ||, corresponding angles are equal.
c. if lines are ||, alternate interior angles are equal.
d. if lines are ||, alternate exterior angles are equal.

3 and 4: B

Step-by-step explanation:

As per the property of traversal lines, when two parallel lines are cut by traversal then the corresponding angles formed are equal.

In given case ∠6 is corresponding angle of ∠8 and ∠8 is corresponding to ∠18.

Hence option B is correct for 3 and statements!

If lines are ||, corresponding angles are equal.

step-by-step explanation:

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
