To find the measures of each angle in the triangle, we use the Triangle Angle Sum Theorem which states that the sum of the angles in a triangle is 180 degrees.
Therefore, we can set up the equation:
(5x - 1) + (8x + 5) + (4x + 6) = 180
17x + 10 = 180
17x = 170
x = 10
Now we can plug in x = 10 to find the measures of each angle:
5x - 1 = 5(10) - 1 = 49°
8x + 5 = 8(10) + 5 = 85°
4x + 6 = 4(10) + 6 = 46°
Therefore, the measures of each angle in the triangle are 49°, 85°, and 46°. So the correct answer is:
46°, 49°, and 85°

To find the measure of the smallest angle, we need to determine which expression (x+10), (x+20), or (x+30) represents the smallest value.
Given that the angles of a triangle must add up to 180 degrees, we can set up the following equation:
(x + 10) + (x + 20) + (x + 30) = 180
3x + 60 = 180
3x = 120
x = 40
Now we can find the measures of each angle:
(x + 10) = 40 + 10 = 50°
(x + 20) = 40 + 20 = 60°
(x + 30) = 40 + 30 = 70°
Therefore, the smallest angle is 50°. The correct response is:
50°

(x + 10) + (x + 20) + (x + 30) = 180
3x + 60 = 180

Now we can find the measures of each angle:
(x + 10) = 40 + 10 = 50°
(x + 20) = 40 + 20 = 60°
(x + 30) = 40 + 30 = 70°
Therefore, the smallest angle is 50°. The correct response is:
50°

To find the measures of the angles in the triangle using the Triangle Angle Sum Theorem, we need to add the angles together and set the sum equal to 180 degrees.
Given that the angles in the triangle are:
Angle a = 4x + 14
Angle b = 5x + 4
Angle c = 6x - 3
We can set up the equation:
(4x + 14) + (5x + 4) + (6x - 3) = 180
15x + 15 = 180
15x = 165
x = 11
Now we find the measures of each angle:
Angle a = 4(11) + 14 = 58°
Angle b = 5(11) + 4 = 59°
Angle c = 6(11) - 3 = 63°
Therefore, the measures of the angles in the triangle are: 58°, 59°, and 63°. The correct response is:
59°, 58°, and 63°

Angle a = 4(11) + 14 = 58°
Angle b = 5(11) + 4 = 59°
Angle c = 6(11) - 3 = 63°
Therefore, the measures of the angles in the triangle are: 58°, 59°, and 63°. The correct response is:
59°, 58°, and 63°
