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:
The answer would be 21.248 miles
2x+4=5x-11
5x-2x=4+11
3x=15
x=5
Answer:
D 2x+x+3x
Step-by-step explanation:
Ian has 2 apples
Jordan has 1 apple
Kate has 3 apples
2apples+1apple + 3 apples
Apples is replaced with x
2x+1x+ 3x
Answer:
33.5
Step-by-step explanation:
ml is 90
ml=23+x+x
(vertical angles is how you find the other x)
23+2x=90
x=33.5
