Let x = shirts, y = trousers, z = hats
Forming Equation 1
4x+4y+2z = 560
Simplifying it to,
2x + 2y + z = 280
Forming Equation 2
9x + 9y + 6z = 1290
Simpifying it to,
3x + 3y + 2z = 430
<span>(1) 2x + 2y + z = 280</span>
(2) <span>3x + 3y + 2z = 430
Doing (2) - (1)
3x + 3y + 2z = 430
2x + 2y + z = 280
Answer is
x + y + z = 150</span>
The answer is 76 and 76 and 28 and 124. All angles of a triangle adds up to 180 degrees. Two angles of an isosceles triangle are congruent or equal to one another.

Answer:
Radius of P = 5 cm
Step-by-step explanation:
Radius (r) of Q = 20 cm
Area of Q = 4 × Area of P
This means that:
Area of the quarter circle (Q) = 4 × Area of the circle (P)
Thus:
¼(πr²) = 4 × πr²
Plug in the values into the equation
¼(π*20²) = 4 × πr²
Find the value of r, which is the radius of P
¼(400π) = 4πr²
Multiply both sides by 4
400π = 4πr²*4
400π = 16πr²
Divide both sides by 16π
400π/16π = r²
25 = r²
Take the square root of both sides
√25 = √r²
5 = r
r = 5
Therefore, the radius of P = 5 cm
