Answer 1

Answer:

The largest possible value of x is 15.

Step-by-step explanation:

Given that the triangle is not obtuse, we know that the widest angle that the three values can add up to is 90 degrees.

We know that that angle is equal to:

30 + 3x + x

so to get a maximum, we can say that it equals 90 degrees and solve for x:

30 + 3x + x = 90

4x = 60

x = 15

So the largest possible value of x is 15.

Answer 2

The largest possible value of x should be considered as the 15.

Calculation of the largest possible value of x:

Since

the triangle is not obtuse, so here widest angle that the three values can add up to is 90 degrees.

So the following equation could be like

30 + 3x + x = 90

4x = 60

x = 15

Hence the largest possible value of x is 15.
