Answer:
the answer is 78 degrees
Step-by-step explanation:
a acute angle is less than 90
Short side length = x Medium side = x + 7 Long side = 5x Total 49, so x + x + 7 + 5x = 49 If you combine like terms: 7x + 7 = 49 Subtract 7 from both sides 7x = 42 Divide both sides by 7 x = 6 inches
Answer:
127.17 cm²
Step-by-step explanation:
Area of a semicircle : 1/2*π*r²π (pi) = 3.14 r (radius) = d (diamater) / 2 => 18/2 = 9 cm
A = 1/2*π*r²
A = 1/2*3.14*9²
A = 1/2*3.14*81
A = 3.14*40.5
A = 127.17 cm²
Therefore, the area of the semicircle is 127.17 cm²
