4) x + x + x = 180°
An equilateral triangle has three sides of equal length. Its interior angles are also equal. Since interior angles of a triangle should sum up to 180°, then each angle is 60°, making each angle congruent with one another.
So if x is equal to one angle and triangles have three angles then,
x + x + x = 180°
or 3x = 180°
Is marks = questions you got wrong?
No, .38 is .08 greater than .3
Answer:
20-11 3/4 = 8 1/4
8 1/4 - 6 2/4 = 1 3/4 left
Step-by-step explanation:
To find the percent 'a' is of 'b', you divide 'a' by 'b' then move the decimal two places to the right.
The equation below represents this.
