The student added 9 1/2 instead of adding -9 1/2
Answer:
54 degrees.
Step-by-step explanation:
So a fun fact is that the exterior angle is equal to the sum of the opposite two interior angles (at least within triangles).
Given this, set these values equal to each other to get the value of a.
d = a + b
2a = (a+10)+44
2a = a + 54
a = 54
The measure of the exterior angle is 54 degrees.
Answer:
You can solve by the formula of area of trapezium. This is h(a+b)/2.
54 = 6(8+b)/2
Thus b = 10cm.
