Question

find x if the angles of a triangle are 5x-60 , 3x+2 , 2x-40​ pls help fast​

Answer 1

Answer:

$\large\boxed{\sf{x=27.8}}$

Step-by-step explanation:

Let the triangle is ∆ABC

Given the three angles as

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

Now, to find the value of x.

We know that,

Sum of all the three angles of a triangle is 180°

Therefore, we will get,

=> A + B + C = 180°

=> 5x - 60 + 3x + 2 + 2x - 40 = 180

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

=> 10x - 98 = 180

=> 10x = 180 + 98

=> 10x = 278

=> x = 278/10

=> x = 27.8

Hence, the required value of x = 27.8
