Can anyone help?? I don't understand.
Andrews [41]
If the height and base are equal, that simply means that b = h, or h = b

and we know the area is 18 m²

\bf \textit{area of a triangle}\\\\
A=\cfrac{1}{2}bh\qquad 
\begin{cases}
b=h\\
A=18
\end{cases}\implies 18=\cfrac{1}{2}\cdot h\cdot  h\implies 18=\cfrac{h^2}{2}
\\\\\\
36=h^2\implies \sqrt{36}=h

PLEASE HELP !!!!!!??
jonny [76]

Answer:

( 1, 35 )

Step-by-step explanation:

y=mx+c

c= y-intercept ( where the graph line crosses the cross line)

c=0

mx = gradient ( rise/run, up/across )

mx = 175/5 ( you could have picked any point in the graph )

mx = 35

the m is useless now so we discard it

y= 35x+0

if x = 1

then y = 35(1)+0

y= 35

at the coordinate x=1 y is 35
