If a = b then a + b = c is
2a = c
OR
2b = c
Answer:
a = 157.7536pi
Step-by-step explanation:
area = pi*circumference²
a = pi*12.56² = 157.7536*pi
however, if pi just equals 3.14:
probably around 495.346304
767,074 rounded to the nearest hundred thousand is 800,000.
Answer: The question isn't finished.
Step-by-step explanation:
2x+38=180
2x=142 (or x+x=142 from which 2x=142)
x=71
The unknown angles are each 71
You know this answer is logical as, since two sides are 21 it hints that we are looking at an equilateral triangle, which means two of its angles will be the same
