Answer 1

Answer:

value of x is 28° .

Step-by-step explanation:

According to the Question

It is given that,

• ∠A = 5x-60°
• ∠B = 2x+40°
• ∠C = 3x-80°

we have to calculate the value of x

As we know that Sum of all angles in a triangle is 180° .

• Sum of angles in a ∆ = 180°

On substituting the value we get

↠ ∠A + ∠B + ∠C = 180°

↠ 5x-60° + 2x+40° + 3x-80° = 180°

↠ 10x -100° = 180°

↠ 10x = 180° + 100°

↠ 10x = 280°

↠ x = 280°/10

↠ x = 28°

• Hence, the value of x is 28° .

Answer 2

Step-by-step explanation:

$\underline \bold{Solution:-}$

we know that :-

• sum of all angle of triangle is equal to 180°

$\angle A +\angle B +\angle C = 180 \degree$

$(5x - 60) + (2x + 40) + (3x - 80) = 180$

$\longrightarrow \: 10x - 100 = 180$

$\longrightarrow \: 10x = 180 + 100$

$\longrightarrow x = \frac{28 \cancel{0}}{1 \cancel{0}}$

$\longrightarrow \: x = 28$

Hence, the value of x is 28°
