Step-by-step explanation:
area of trapezoid=(a+b)×h divided by 2
=(9+19)×4 divided by2
=28×4 divided by2
=112 divided by 2
=56m square
Answer:
43°
Step-by-step explanation:
For triangle ABC:
A = C so all we need to do is to calculate the value of B
The measure of angle ABD is given as 17° so the measure of angle EBC must be 17° as well
Since DBE is an equilateral triangle angle is DBE = 60°
17 + 17 + 60 = 94 this is the measure of angle B
The sum of interior angles in a triangle is equal to 180
A + B + C = 180
A + C + 94 = 180
A + C = 86 since A = C we divide 86 by 2
C = 43°
Based on the central angle theorem, the measure of angle AEB is: 140°.
<h3>What is the Central Angle Theorem?</h3>
According to the central angle theorem, the measure of an intercepted arc = measure of the central angle.
Arc AB = 140° [intercepted arc]
Angle AEB is the central angle.
Thus, based on the central angle theorem, the measure of angle AEB is: 140°.
