Answer:
48.3 cm^2
Step-by-step explanation:
The area of the enclosing square is that of a square 15 cm on a side, so is ...
square area = (15 cm)^2 = 225 cm^2
The white area is that of a quarter-circle of radius 15 cm, so that area is ...
quarter-circle area = (1/4)πr^2 = (π/4)·(15 cm)^2 = 56.25π cm^2 ≈ 176.7 cm^2
Then the yellow area is the difference ...
yellow area = square area - quarter-circle area
= (225 cm^2) - (176.7 cm^2)
yellow area = 48.3 cm^2
Hello!
Tangent lines have only one point on the circle, meaning they form straight angles with the edge of the circle. The radius goes from the center of the circle to the point where the tangent line is on circle, creating a right angle.

We need more information to answer this question, I'd gladly help if there was some more data.
Step-by-step explanation:
SAS because they tell you that two sides anre congruent and also one angle is
<span>Three numbers can be defined as x, y, and z.
x + y + z = 64
y = x+3
z = 2x - 11
.
substitute for y and z
x + (x+3) + (2x-11) = 64
4x -8 = 64
4x = 72
x = 18
.
y = x+3 = 21
z = 2x -11 = 2(18) -11 = 36-11 = 25
.
x + y + z = 18 + 21 + 25 = 64
Correct.
.
Answer: The three numbers are 18, 21, and 25.</span>
