Question

The measures of a triangle are shown below. sovle for x​

Answer 1

Answer:

$x=16$

Step-by-step explanation:

In a triangle the sum of all angle measures will always equal 180 degrees.

$A+B+C=180$

From the information given we know that the angle measures are:

$A= 90, B=(5x-3), C=(x+9)$

When you input this into the equation above you get:

$90+(5x-3)+(x+9)=180$

First, subtract 90 from both sides

$(5x-3)+(x+9)=90$

Next let's combine like terms

$6x+6=90$

Subtract 6 from both sides

$6x=84$

divide both sides by 6

$x=16$
