Answer:
Angles of a rhombus equal 360. Bisected adjacent angles are equal. Opposite angles are equal. Same side angles are supplementary
Step-by-step explanation:
One angle is 40, the adjacent bisected angle is also 40. Opposite angles are equal so the opposite angle is 80 degrees (the bisected angles are each 40).
Same side angles are supplementary (add up to 180 degrees) So the supplementary angle of the 80 degree angle is 100 degrees, and its opposite angle is also 100 degrees. The angles of a rhombus add up to 360...80+80=100+100= 360.
Answer:
720 = x +133+138+148+95+105
x = 101
Option C: 
is the correct answer.
Explanation:
The given expression is 
We need to determine the factor of the expression.
Now, let us break the given expression into two groups.
Hence, we get,
Simplifying, we get,
Let us factor out 7g from the term 
Hence, we have,
Similarly, let us factor out -6h from the term 
Thus, we have,
Now, we shall factor out the term 
, we get,
Thus, the factorization of the given expression is
Therefore, Option C is the correct answer.
The measure of the seventh <em>interior</em> angle of the heptagon is 124°. (Correct choice: C)
<h3>What is the measure of the missing interior angle in a heptagon?</h3>
Heptagons are polygons with seven sides, seven vertices, seven <em>interior</em> angles and seven <em>central</em> angles. Herein we know the value of the sum of six interior angles and we need to know the measure of the seventh <em>interior</em> angle. We can determine the measure of the seven interior angles by using the following expression:
θ = (n - 2) · 180°, where n is the number of sides of the polygon. (1)
If we know that n = 7, then sum of the internal angles in the heptagon is:
θ = (7 - 2) · 180°
θ = 900°
And the measure of the final interior angle is found by subtraction:
θ₇ = 900° - 776°
θ₇ = 124°
The measure of the seventh <em>interior</em> angle of the heptagon is 124°. (Correct choice: C)
