IN ORDER TO FIND THE ANSWER:
Add up two of the values. If they are greater than the third, the lengths can make up a triangle.
3 + 9 = 12
12 > 14? No
3 + 5 = 8
8 > 7? Yes
1 + 2 = 3
3 > 3? No
4 + 4 = 8
8 > 8? No
The answer would be B.
Answer:
The three unknown angles X, Y , and Z are:
X = 40, Y = 20, and Z = 120
Step-by-step explanation:
Let's name X the measure of the first angle, Y the measure of the second one, and Z that of the third one.
Then we can create the following equations:
X = 2 Y
Z = 100 + Y
and
X + Y + Z = 180
So we use the first equation and the second one to substitute for the variable X and Z in the thrid equation:
2 Y + Y + (100 + Y) = 180
4 Y + 100 = 180
4 Y = 80
Y = 80/4 = 20
Then X = 40, Y = 20, and Z = 120
Answer:
Circumference: 37.68
Area: 113.04
Step-by-step explanation:
the formula to find the circumference is 2 x 3.14 x r
r is the radius so you plug in 6 for that
2 x 3.14 x 6 = 37.68
the formula to find the area of a circle is 3.14 x r ²
r is still the radius so you plug in 6 for that
3.14 x 6² = 113.04
Well that symbol is an indention or multiply sign of expression
The simplified version is 25/18
