3X + 5X = 136
8X = 136
X = 17
Numbers are 51 and 85
Answer:
B is your correct answer
Step-by-step explanation:
Answer:
60°
Step-by-step explanation:
Am equilateral triangle is a triangle that has all its sides and angles equal. Note that an equilateral triangle has 3 sides and angles.
Let the angles be a, b and c
The sum of angle in a triangle is 180°, hence;
a+b+c = 180°
Since a = b = c
The equation becomes;
a+a+a = 180°
3a = 180
a = 180/3
a = 60°
Hence the measure of the angles of an equilateral triangle is 60° for the three angles.
For a line to be parallel it has to have the same slope as the original line. so the slope is 1/2
