Answer:
SAS
Step-by-step explanation:
ΔABD ~ ΔECD is similar through:
S - because ED = CD (Given)
A - same angle ∠D (Statement 2)
S - because AD = BD (Given)
Cheers!
Start by solving inside the parentheses. According to PEMDAS you will divide 10 and 2 first. Divide 10 by 2 and you will have: 8 + (5)(4) - (6 + 5) + 44.
Now finish solving inside the parentheses and add 6 and 5.
8 + (5)(4) - (11) + 44, multiply 5 and 4.
8 + 20 - 11 + 44, then solve from left to right.
61 is the answer.
18 is the answer to the question because it would be 6x3 which is 18

Answer:
shaded/square = (50π cm²)/(400 cm²) = π/8
Step-by-step explanation:
The quarter circle has area ...
A = (1/4)(πr²) = π/4(20 cm)² = 100π cm²
The half-circle has area ...
A = (1/2)(πr²) = π/2(10 cm)² = 50π cm²
Then the area of the shaded portion is ...
shaded = 100π cm² -50π cm² = 50π cm²
__
The area of the square is ...
A = s² = (20 cm)² = 400 cm²
Then the ratio of interest is ...
shaded/square = (50π cm²)/(400 cm²) = π/8
