Answer:

(6,2)

Step-by-step explanation:

Since $y=x-4$ , we can substitute this into the second equation so that there is only one variable that we can solve for.

$4x+(x-4)=26$

$5x-4=26$

$5x=30$

$x=6$

Now we can plug this back into the first equation.

$y=(6-4)$

$y=2$

Express the area of the triangle shown below in terms of b and θ only.

Paul [167]

Given a right triangle with base, b and height, h with the angle opposide side h as θ.

The area of a triangle is given by
$A= \frac{1}{2} bh$

But,
$\tan\theta= \frac{h}{b} \\ \\ \Rightarrow h=b\tan\theta$

Therefore, the area of the triangle in terms of b and θ only is given by
$A= \frac{1}{2} b(b\tan\theta)= \frac{1}{2} b^2\tan\theta$
