This is an equilateral triangle (a triangle with 3 equal/congruent sides and 3 congruent angles)
Since you know the sides have to be the same/equal to each other, you can set the sides equal to each other (you can just do two because all of the sides are suppose to be the same anyways)
BC = AC
5x = 3x + 6 Subtract 3x on both sides
2x = 6 Divide 2 on both sides
x = 3
18 - 5.7 = 12.3
12.3 - 8.8 = 3.5
3.5 to a fraction = 3 1/2
So the answer = 3 1/2
Hope this helps >.<
Answer:
Correct option is
A
49m
The circumference of a circular field is 308m
Therefore, 2πr=308
⇒r=
2×22
308×7
⇒r=49m
Step-by-step explanation:
here you go
From x equals five to nine, the y value changes as follows
+10,+2,+1,+3
Assuming that "average" implies the mean, the sum of all four values is 15. Then divide 15 by the four values added = 15/4 = 3 3/4 or 3.75
