Answer:

140.3°

Step-by-step explanation:

Given the following angles

Interior angles are 110° and x°

Exterior angle = (4x+7)°

Using the triangular property which says that the sum of interior angle of a triangle is equal to its exterior angle, we have:

110 + x = 4x + 7

110 - 7 = 4x-x

103 = 3x

x = 103/3

x= 34.3°

Get the exterior angle

Exterior angle = 4x+7

Exterior angle = 4(34.3)+7

Exterior angle = 137.3+7

Exterior angle = 140.3°

Hence the measure of the exterior angle shown is 140.3°
