Answer:
36cm
Step-by-step explanation:
38 × 2 = 76
148 - 86 = 72
72/2 = 36
3x° is 60° , 2x° is 40° and 4x° is 80°
<h3>
How to determine the angles</h3>
Note that the sum of angles in a triangle is 180°
Solve for x in the triangle
Then,
3x° +2x° + 4x° = 180°
Add the x°
9x° = 180°
Divide both sides by 9
x° = 180÷ 9 = 20°
If x° = 20
Then 3x° = 3× 20 = 60°
2x° = 2 × 20 = 40°
4x°= 4× 20 = 80°
Therefore, 3x° is 60° , 2x° is 40° and 4x° is 80°
