When you have two parallel lines being cut by a transversal, you can use the next statements for the angles:
The measurement of the angles in green is the same (are congruents)
The measurement of the angles in blue is the same (are congruents)
An angle in green is a complementary angle with an angle in blue. (The addition of the two angles has to be 180º)
You know that:
As the angle 3 is congruent with angle 2:
Answer:
No picture
Step-by-step explanation:
We can convert the fraction to a denominator of 100, since percents are parts of 100.
39 * 2 = 78
50 * 2 = 100
So we have 78/100 or 78%
In math and and other types of school stuff :) if that's what your asked
Answer:
If you know the base and area of the triangle, you can divide the base by 2, then divide that by the area to find the height. To find the height of an equilateral triangle, use the Pythagorean Theorem, a^2 + b^2 = c^2.
