Answer:
(a)
(b)
Step-by-step explanation:
A(-3,0)
B(0,6)
2x-y+6=0
a=2, b=-1, c=6
x0=0, y0=0
For cases like these, we need to find the base then multiply it by the height. Let’s separate the triangle and the rectangle of the base
Triangle:
1/2(6*9) = 27
Rectangle:
5 * 9 = 45
Total base:
45+ 27 = 72
Now for the area:
72 * 12 = 864 m^3
864 m^3 would be the volume.
Answer:
The perimeter of triangle is 30ft.
Step-by-step explanation:
First you have to find the value of a using Pythogoras Theorem, a² + b² = c² where a and b is the sides and c is the hypotenuse :
Let b = 12,
Let c = 13,
Next you have to find the perimeter of triangle by adding all the sides together :
Answer:
D. 24
Step-by-step explanation:
Angles are the same, so 84 = 3x.
To get x alone, you divide 3 by both sides.
84/3 = 24
24 = x.
