The measure of angle F is 140
What is a right-angled trapezoid?
Two consecutive right angles make up a right trapezoid, also known as a right-angled trapezoid. The trapezoidal rule employs right trapezoids to calculate the areas under a curve. An obtuse trapezoid has one acute and one obtuse angle on each base, whereas an acute trapezoid has two consecutive acute angles on its longer base edge.
Given
Sum of all angles of trapezoid = 360
9x + 14x + 4x+ 90 = 360
27x + 90 = 360
27x = 270
x = 10
F = 14x = 14* 10 = 140
Therefore, The measure of angle F is 140.
