To find the sum of the interior angles of a heptagon, divide it up into triangles ... There are five triangles... Because the sum of the angles of each triangle is 180 degrees... We get.
-20.01
-20.02
-20.03
and so on
all the way to 20.99
Answer:
Step-by-step explanation:
Add 11 to both sides of the inequality to make - 4x stand alone
Divide both sides by - 4
Reverse the signs
We have the final answer as

Answer: ZB = 48 degree
Explanation:
Complementary angle means 2 angel add together and create a right angle (90 degree).
Thus, ZA + ZB = 90 degree
But ZA = 42 degree
=> 42 degree + ZB = 90 degree
=> ZB = (90 - 42)degree
=> ZB = 48 degree
