Final answer:
The measurement of angle PQT is given by (9x + 34) and can be found by substituting the value of x into the expression. The measurement of angle PQT if it is (9x + 34) is 79°. So, the correct answer is b) 79°.
Step-by-step explanation:
In order to determine the measurement of angle PQT, the expression (9x + 34) is provided, where x represents a variable.
The approach involves substituting the given value of x into the expression to obtain the angle's specific value.
For instance, if x equals 5, the calculation becomes (9(5) + 34), resulting in an angle measurement of 79°.
Thus, the correct solution corresponds to option b) 79°.
This method underscores the importance of assigning a numerical value to the variable in the given expression, allowing for the precise determination of the angle's measurement.
By systematically substituting different values for x, one can discern the varying magnitudes of angle PQT based on the provided mathematical expression, ultimately arriving at the correct answer of 79° in this particular scenario.
Therefore, the correct answer is b) 79°.
