Answer:
h = 7.1 cm
Step-by-step explanation:
To find the height of the triangle, we can first find the area of the triangle using the Heron's formula:
Where a, b and c are the sides of the triangle and p is the semi perimeter of the triangle:
So the area of the triangle is:
Now, to find the height, we can use the following equation for the area of the triangle:
The height draw in the figure is relative to the side of 17 cm, so this side is the value of base used in the formula. So we have that:
Rounding to the nearest tenth, we have h = 7.1 cm

Answer:
First odd number = 13
Second odd number = 15
Step-by-step explanation:
Let
First odd number = 2x + 1
Second odd number = 2x + 3
According to given conditions:
32 + 2x + 1= 3 (2x + 3)
33 + 2x = 6x + 9
Taking terms with x to left and constants to right
2x - 6x = 9 - 33 (sign of transferred terms will be changed)
-4x = -24
Dividing both sides by -4
x = -24/-4
x =6
So,
First odd number = 2x + 1 = 2*6 + 1 = 12 + 1 =13
Second odd number = 2x + 3= 2*6 +3= 12 + 3 = 15
I hope it will help you!
