Question

Find the angle of the triangle if A contains 80 degree b is 2x and c is 3x​

Answer 1

Answer:

Find the angle of the triangle if A contains 80 degree b is 2x and c is 3x

Step-by-step explanation:

It is important to know that the angles in a triangle add up to 180 degrees. Here is a slightly different way of doing the problem:

Let First angle=80 second angle = 2x and the 3rd angle=3x

1) Set up the equation like this: 1st angle +2nd angle+ 3rd angle=180 Then use substitution:

2) 80 + 2x + 3x = 180 Collect like terms.

3) 80 + 5x =180 Isolate "5x" on the left side of equation by getting rid of 80 from both sides.

4) Then solve for "x" by dividing both sides of the equation by the number (coefficient) next to it. Then you can solve for the second and third angles through substitution.

Answer 2

$\bf\large\underline\red{Answer:-}$

➤ A = 80°

➤ B = 2x = 2×20° = 40°

➤ C = 3x = 3×20° = 60°

$\bf\large\underline\green{Solution:-}$

➤ The sum of all three angle of triangles is 180°.

➤ A + B + C = 180°

➤ 80° + 2x + 3x = 180°

➤ 5x = 100°

➤ x = 20°

➤ B = 2x = 2×20° = 40°

➤ C = 3x = 3×20° = 60°
