Answer:
26.7
Step-by-step explanation:
The formula of an area of a triangle:
[tex]A=\dfrac{1}{2}bh=\dfrac{bh}{2}[/tex]
b - base
h - height
We have b = 15, A = 200.
Substitute:
[tex]200=\dfrac{15h}{2}[/tex]
[tex]200=7.5h[/tex] divide both sides by 7.5
[tex]\dfrac{200}{7.5}=\dfrac{7.5h}{7.5}[/tex]
[tex]h\approx26.7[/tex]
