Answer:
28
Step-by-step explanation:
We use the concept of similarity to find the value of X.
Δ APR ≡ ΔCDR
∴ AR/CR = PR/DR
(10+x)/x = (15+42)/42
42(10+x) = 57x
420 + 42x = 57x
57x - 42x = 420
15x = 420
x = 420/15
= 28
Answer:
Step-by-step explanation:
Radius of outer circle = R = 9 cm
Radius of inner circle = r = 5 cm
Area of the shaded region = area of the outer circle - area of the inner circle.
= πR² - πr²
= π(R² - r²) = 3.14*(9² - 5²)
= 3.14 * (81- 25) = 3.14 * 56
= 175.84 cm²
Answer:
We have (2/3)x(1-1/4) - 1/4 = (2/3)x(3/4) -1/4 = 6/12 = 1/4 = 1/2 -1/4 = 2/4 - 1/4 = 1/4 do I bring in between;
Step-by-step explanation:
Slope = (-8 - 7)/(4 - 9)
