Answer:
Step-by-step explanation:
I am assuming that by "interior" angle you do not mean the central angle.
This is a 10-sided polygon, a decagon. That means that there are 10 triangles that can extend from the center, with their sides being equal to the radii of the decagon. If we extract one of these triangles we can find what the interior angle is. The vertex angle measures 360/10 which is 36.
Split this triangle in half from the vertex to the base, creating a right triangle. The vertex angle is also split in half, making this angle (the vertex angle is the one at the top of the triangle) 18 degrees. We already know that one angle inside this right triangle is 90 (definition of a right triangle) and to find the other one, we apply the Triangle Angle-Sum Theorem:
180 - 18 - 90 = 72 degrees. That is the measure of the base angle that is NOT the right angle, obviously.
1 recipe = 2/3 cup of butter.
3/4 recipe = 3/4 x 2/3 = 1/2 cup of butter
Answer: 1/2 cup of butter

Answer:
59 cm
Step-by-step explanation:
The area is the product of length and width. Using the given numbers, we have ...
A = LW
4779 cm² = (81 cm)W
W = (4779 cm²)/(81 cm) = 59 cm
The width of the window is 59 cm.
Answer:
X= 4. Y = 3.
Step-by-step explanation:
If you have a graphing calculator, put the first equation into Y1. And second equation into Y2. Then, find the intersection of the two equations. That's how you find your answer.
