Find the measure of the missing angles.

d
69°
e
f

To find the measure of the missing angles, we need to use the fact that the sum of all angles in a triangle is 180 degrees.

Given that angle d = 69 degrees, we can find the measure of angles e and f by subtracting the known angles from 180 degrees.

Let's denote the measure of angle e as x and the measure of angle f as y.

69° + x + y = 180°

To find x and y, we need to solve for them by rearranging the equation:

x + y = 180 - 69
x + y = 111

Since the sum of angles e and f is 111 degrees, we cannot determine the exact measure of each individual angle with the information given.
