Answer:
15 feet
Step-by-step explanation:
The question talks about;
- A rectangular flower bed whose dimensions are 12 ft by 9 ft
We are required to determine the length of the diagonal
To answer the question, we need to know the following;
- All the angles in a rectangle are right angles
- A diagonal divides a rectangle into two right-angled triangles
- The dimensions of the rectangle acts as the legs of right angled triangle.
Therefore;
Using Pythagoras theorem;
a² + b² = c²
Where, c is the hypotenuse (in this case the diagonal)
a and b are the shorter sides of the right-angled triangle
Therefore;
c² = 12² + 9²
c² = 144 + 81
= 225
c = √225
= 15
Therefore, the length of the diagonal is 15 feet
It's pretty simple if you just read through it carefully. Here you go.
Answer:
Step-by-step explanation:
8. 7.5 Goes up by 2.5.
9. 7.3 Goes down by 2.1
10. 116/3
Answer:
negative 3
Step-by-step explanation:
so if you know basic algebra you can make an equation 2x+10=4 simplify it to x+5=2 and if you subtract 5 from both sides you end up with x=negative three
