Let x be the measure of the second angle. Then we have:
43 + x + 2x = 180 (the sum of the angles in a triangle is 180 degrees)
Simplifying this equation, we get:
43 + 3x = 180
Subtracting 43 from both sides, we get:
3x = 137
Dividing both sides by 3, we get:
x = 45.67
So the second angle is approximately 45.67 degrees. To find the third angle, we can subtract the sum of the first two angles from 180 degrees:
180 - 43 - 45.67 = 91.33
Therefore, the third angle is approximately 91.33 degrees.
One angle of a triangle is 43° and the second angle is twice as big as find the third angle?
