Question

What is the x value of the triangle 3x-5, 2x+20, 4x-30

Answer 1

Answer:

The answer is 25

Step-by-step explanation:

Answer 2

Answer:

x = 21.7°

Step-by-step explanation:

We know that the sum of the three angles in triangle add up to a total of 180°.

So adding the given expressions of angles and putting them equal to 180 to find the value of x:

$(3x-5) + (2x+20) +(4x-30)= 180$

$4x+3x+2x+20-30-5=180$

$9x=180+30-20+5$

$9x=195$

$x=\frac{195}{9}$

$x=21.7$

Therefore, the value of x in a triangle with angles 3x-5, 2x+20, 4x-30 is equal to 21.7°.
