Answer:
P = 48 feet
A = 84 square feet
Step-by-step explanation:
use the Pythagorean Theorem 2 times to find the bases of the two triangles created by the height of eight
1st Δ : one leg is 8 and the hypotenuse is 10
a² + 8² = 10²
a² + 64 = 100
a² = 36
a = 6
2nd Δ : one leg is 8 and the hypotenuse is 17
b² + 8² = 17²
b² + 64 = 289
b² = 225
b = 15
Perimeter = 10 + 17 + 6 + 15 = 48 ft
Area = 1/2(8)(6 + 15) = 4(21) = 84 sq ft
Answer:
48cm
Step-by-step explanation:
The perimeter of first shape is 36cm. There are 3 semi circle (curves).
Therefore,
3 curves of semicircle (arc length) = 36
1 curve of semicircle (arc length) = 36/3
= 12cm
In picture 2,
4 semicircles (They've mentioned that they used the same semicircle for the 2nd shape also)
So,
4×12 = 48cm
Answer:
A repeating decimal can be written as a fraction using algebraic methods, so any repeating decimal is a rational number.
Marco is wrong cuz its not repeating
Answer:
it's a scalene triangle
