Answer:
A = 11.7
Step-by-step explanation:
Just substitute the known values into the equation:
Let the measures of three angles be 2x, 9x, 4x
Sum of the angles of a triangle = 180
2x+9x+4x = 180
15x = 180
x = 180/15 = 12
First angle = 2x = 2*12 = 24°
Second angle = 9x = 9*12 = 108°
Third angle = 4x = 4*12 = 48°
I hope it is helpful:D
Step-by-step explanation:
The longest side of a triangle must be less than the sum of the shorter sides.
If 8 and 12 are the shorter sides, and c is the longest side, then:
c < 8 + 12
c < 20
If c and 8 are the shorter sides, and 12 is the longest side then:
12 < c + 8
4 < c
The range of possible lengths for the third side is:
4 < c < 20
Answer: the answer will be 26x
Step-by-step explanation:
Answer:
A because when you add the angles up it has to equal 180
