Answer:
A. 93°
Step-by-step explanation:
The inscribed angle has half the measure of the arc it subtends.
∠Y = 186°/2 = 93°
The measure of angle XYZ is 93°.
80 is the fixed amount because it is a cost before you get their services. So basically the Y intercept. It is if you pay for an 80$ membership fee and then you are charged per month.
To find one interior angle of a regular octagon first we need to find the sum of all interior angles of the octagon.
There is a formula to find the sum of all interior angles. The formula is
, where n is the total number of sides of the polygon.
For octagon the total number of sides = 8.
So the sum of interior angles of the octagon
= 
= 
= 
Now for regular octagon all the angles are equal.
There are total of 8 angles for the octagon. As all angles are same, we can find one interior angle by dividing the sum of interior angles by the number of angles.
So, the measurement of one interior angle
= 
= 
We have got the required answer here. The measure of one interior angle of regular octagon is
.
So, the correct option is option D.

Answer:
30.6 cm²
Step-by-step explanation:
The area of the parallelogram is simply the sum of the areas of the component three shapes - the square and the two triangles.
Area of square = 4.5 cm × 4.5 cm = 20.25 cm²
Area of two triangles = 2 ×(1/2) × 2.3 cm × 4.5 cm = 10.35 cm²
Area of parallelogram = 20.25 cm² + 10.35 cm² = 30.6 cm²
