Answer:
Altitude = 3
Step-by-step explanation:
Given the area of a triangle as 15, with a length of 10:
We can use the following formula for finding the area of a triangle:
Area (A) = ½bh
Where:
Base (b) = 10
Height (h) or altitude = unknown
Substitute the given values into the formula:
Area (A) = ½bh
15 = ½(10)h
15 = 5h
Divide both sides by 5 to solve for h:
[tex]\displaystyle\mathsf{\frac{15}{5}\:=\:\frac{5h}{5} }[/tex]
h = 3
Therefore, the length of the altitude or height of the given triangle is 3.
