the missing line is 0.4
all triangles equal 180 (or 18.0)
7.1 + 10.5 = 17.6
18.0 - 17.6 = 0.4
Answer:
I need the values of either X or Y to solve this. I can solve for what X is though.
Step-by-step explanation:
A: X = -12
B: X =78
C: X = 12.13
I hope this helps you, but since both X and Y are unknown variables, you can't solve it, only simplify (which it already is.)
Answer:
Non linear( it doesn't go through the 0
Step-by-step explanation:
<u>Given</u>:
The satang coin from Thailand has a radius of about 7 mm.
We need to determine the diameter and circumference of the coin.
<u>Diameter of the coin:</u>
The diameter of the coin can be determined by multiply the radius by 2.
Thus, we have;

Substituting r = 7, we get;


Thus, the diameter of the coin is 14 mm.
<u>Circumference of the coin:</u>
The circumference of the coin can be determined using the formula,

Substituting
and
, we get;


Thus, the approximate value of the circumference of the coin is 43.96 mm
