Answer: Longest side = 19 ft
Explanation:
We are given a triangular shaped with two equal sides.
Let length of equal side be x ft
Third side is 4 ft longer than equal side.
Third side = (x+4) ft
Three sides of triangular garden are x, x and x+4.
The perimeter of triangular garden is 49 ft.
Perimeter of triangle = Sum of all three sides
Perimeter of triangle = 49 ft
x+x+x+4=49
3x=49-4
3x=45
x=15 ft
Longest side = x+4 => 15+4
Longest side = 19 ft
The correct answer is A. EH.
1) -27+1÷ -2 = -26÷ -2 =13
2) 60/-10 = -6
Answer:
It is B. H = 3d
Step-by-step explanation:
I got it right :)
Given:
length = 6
width = 5
height = 9
Diagonal of a rectangular prism = √(l² + w² + h²)
d = √ 6² + 5² + 9²
d = √ 36 + 25 + 81
d = √ 142
d = 11.916 ROUNDED TO NEAREST WHOLE UNIT D. 12 CM.
Given:
Pyramid base = 12 cm
height = 8 cm
We can use the Pythagorean theorem to look for the slant height because it is the hypotenuse of a right triangle.
a² + b² = c²
a is the height ; b is the base ; c is the slant height.
b = 1/2 of the pyramid base.
b = 12/2 = 6 cm
8² + 6² = c²
64 + 36 = c²
100 = c²
√100 = √c²
10 = c Answer is letted D. 10 cm.
