Answer:
24
Step-by-step explanation:
Answer:
for the triangle on top on side is 8 one side is 4 so if we use the theorem
64+16=80
a=9
so
Side a = 19.8242
Side b = 17.66349
Side c = 9
Angle ∠A = 90° = 1.5708 rad = π/2
Angle ∠B = 63° = 1.09956 rad = 7/20π
Angle ∠C = 27° = 0.47124 rad = 3/20π
Area = 79.48573
Perimeter p = 46.4877
Semiperimeter s = 23.24385
he know that the angle of each corner is 90º because the two lenghths and the two wides are parallel this means that the figure is a rectangle. so the solution isnumeral A)
Y^2 + z^2 = x^2 (the third one)
