Answer:

The value of x is 30.

Step-by-step explanation:

The value of x is 30 because 3*30 equals 90 and 90 minus 15 is equal to 75. The total is equal to the angle ST.

Answer:

Step-by-step explanation:

We know that in this case, since this is an intersection, the opposite sides are the same. Therefore, we can make a equation like this:

75 = 3x-15

Then we get:

90=3x

30=x

Does anyone know how to do this?

Answer:

$\boxed{\tt x=\sqrt{85} }$

Step-by-step explanation:

When making a right triangle with 2 points, the distance is the hypotenuse which can be represent as "x"

To find the distance we can use the Pythagorean theorem.

$\boxed{{\tt a^2+b^2=c^2}}$

→ $\tt a=9$

→ $\tt b=2$

→ $\tt c=x$

Let's Plug in the side lengths:

$\tt 9^2+2^2=x^2$

Evaluate 9²= 81 and 2²= 4:

$\tt 81+4=x^2$

Now, add 81+4= 85

$\tt 85=x^2$

Take the square root of both sides:

$\tt x=\sqrt{85}$
