Math Problem Statement

Which equation can be used to solve for x based on the given angles in the diagram? Solve for x.

Solution

Let's analyze the image and solve the problem step by step.

Given:

  • The diagram shows angles SQR=16\angle SQR = 16^\circ and PQS=(5x37)\angle PQS = (5x - 37)^\circ.
  • PQS\angle PQS and SQR\angle SQR form a straight line, so their sum should be 180180^\circ.

Step 1: Set up the equation

Since PQS+SQR=180\angle PQS + \angle SQR = 180^\circ, we can write: (5x37)+16=180(5x - 37)^\circ + 16^\circ = 180^\circ

Step 2: Simplify the equation

Combine like terms: 5x37+16=1805x - 37 + 16 = 180 5x21=1805x - 21 = 180

Step 3: Solve for xx

Add 21 to both sides of the equation: 5x=2015x = 201 Now, divide by 5: x=40.2x = 40.2

Step 4: Verify the equation given

From the multiple choices shown:

  1. 9x36=909x - 36 = 90
  2. 9x40=909x - 40 = 90
  3. 9x+49=909x + 49 = 90
  4. 9x+36=909x + 36 = 90

The equation we derived does not exactly match any of these provided choices, so it seems there might be a mix-up. However, based on the logical derivation of x=40.2x = 40.2 using the correct relationship of the angles, our calculated value should be used.

Final Answer:

The correct value for xx is approximately 40.2.
