Answer:
See below;
Step-by-step explanation:
1 . Consider the step below;
<em>Thus, Solution ; g = 37 degrees</em>
2 . Knowing that these circle are " circumscribed " in this rectangle so that they are perfectly aligned, considering the length of this rectangle to be 20 inches, let us determine the radius;
<em>Thus, Solution ; 25π</em>
3. Let us first consider the given, then solve for the value of a, b, e;
<em>Solution; a = 34°, b = 90°, e = 56°</em>
Answer:
The area of A is nine times the area of B.
Step-by-step explanation:
The ice cream cone consists of a semi-circle with a diameter of 10 cm and a triangle with a base of 10 cm and height of 12 cm.
The area of a semi-circle is half the area of a full circle, so we can find it by using:
If the diameter of the circle is 10 cm, then the radius is 5 cm. Plug in the known values:
or about 39.25
The area of a triangle is:
So we can plug in the known values to find the area to be:
When we add the areas of the two sections together, we get an exact answer of:
(60 + 12.5pi) cm^2
or about
99.25 cm^2
Answer:
x = 8
Step-by-step explanation:
These two angles both containing an x are equal. They are called vertically opposite angles.
2x + 62 = 5x + 38 Subtract 2x from both sides
2x-2x + 62 = 5x -2x + 38 Combine
62 = 3x + 38 Subtract 38 from both sides
62 - 38 = 3x - 38 + 38 Combine
24 = 3x Divide both sides by 3
24/3 = 3x/3 Combine
8 = x
