Question

look at the diagram
which equation can be used to solve for x?
$12x + 42 = 90$ $12x + 32 = 90$ $17x + 37 = 90$ $17x - 37 = 90$
solve for x.
$x = $

Explanation:

Step1: Identify right angle sum

The two angles add to 90°:
$37 + (12x + 5) = 90$

Step2: Simplify left side

Combine constant terms:
$12x + (37 + 5) = 90$
$12x + 42 = 90$

Step3: Solve for x

Isolate the variable term:
$12x = 90 - 42$
$12x = 48$
Divide by 12:
$x = \frac{48}{12}$

Answer:

1. The correct equation is $12x + 42 = 90$
2. $x = 4$
