Yes, there is a fraction because when solving the equation you need to find Q. So to find Q you will need to divide
Step-by-step explanation:
Below is an attachment containing the solution.
Answer:
a = 49°
Explanation:
You use the rule ‘exterior angle of a triangle’ which states that the exterior angle is equal to the sum of the two opposite interior angles.
To put it mathematically:
a + a = a + 49° (Ext angles of triangle)
a = a - a + 49°
a = 49°
