Answer:
45, 117,18
Step-by-step explanation:
The ratio of the three angles are
5:13:2
Multiply that by x
5x 13x 2x
The sum of the three angles is equal to 180.
5x+13x+2x = 180
Combine like terms
20x = 180
Divide by 20
20x/20 = 180/20
x = 9
The angles are
5x = 5*9 = 45
13x = 13*9 = 117
2x=2*9 = 18
Answer: Hello there!
We know that the angles of a triangle have a ratio of:
5:13:2
This means that if we have a variable x, the angles are:
a1 = 5x, a2 = 13x and a3= 2x
We also know that if we add up the 3 angles of a triangle, the result is 180°
this says:
a1 + a2 +a3 = 180°
5x + 13x + 2x = 180°
20x=180°
x = 180°/20 = 9°
now we can replace x in the previous equations and obtain the values of a1, a2 and a3
a1 = 5x = 5*9° = 45°
a2 = 13x = 13*9° = 117°
a3 = 2*9° = 18°
