Answer:

X = 20

Step-by-step explanation:

180 - 74 = 106 ( angles on a straight line add up to 180)

180 - (106 +54)

X = 180 - 160

X = 20 ( angles in a triangle add up to 180)

The answer is 20°

if all the angles in a triangle add up to 180°
then all you have to do is subtract the outer 74° from 180° to find the inner angle and then add your solution to 54° and subtract from 180 again
