You can make 18 fruit baskets with 8 apples, 6 oranges, and 5 pears in each
X= 20 & Y= 70 in right-angled triangle .
What is right angle triangle?
- A right-angled triangle is a particular kind of triangle in which one of the angles is 90 degrees.
- The combined angles of the other two are 90 degrees. Perpendicular and the triangle's base make up the sides that the right angle is formed from.
- The longest of the three sides, known as the hypotenuse, is the third side.
2X + 140 = 180
2X = 40°
X = 20°
X + Y = 90°
Y = 70°

Let's call the midpoint of GF M.
MF = 16/2 = 8
KF = 25.89
MK = sqrt(25.89^2 - 8^2)
MK = 24.62
MKF = 8 * 24.62 / 2 = 98.48 square units for one triangle
There are 20 of those triangles that make up the decagon.
Therefore the total area = 20(98.48) = 1969.6 which would be option C
Answer:
9
Step-by-step explanation:
This is a right triangle. We can use the Pythagorean theorem to determine the missing side.
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 12 ^2 = 15^2
a^2 +144 =225
a^2 = 225-144
a^2 = 81
Taking the square root of each side
a = 9
