Answer:
x = 16
Step-by-step explanation:
(x+2) + (7x+2) + (3x) = 180
<em>Add like terms</em>
7x + x + 3x = 11x
2 + 2 = 4
11x + 4 = 180
<em>Subtract 4</em>
11x + 4 = 180
11x = 176
<em>Divide by 11</em>
11x = 176
x = 16
There is a 50% chance that a randomly chosen number between 1 and 100 will be even.
a. vertical angles are congruent
b. congruence of angles is transitive
c. if two lines are cut by a transversal such that alternate interior angles are congruent, then the lines are parallel
5 x 20 is 100
3 x 20 is 60
60%
.60
Answer:
Both 70 degrees
Step-by-step explanation:
The base angles of an isosceles triangle are congruent.
The other 2 angles are each (180 - 40) / 2
= 70 degrees
