Suppose an isosceles triangle abc has a=pi/4 and b=c=4. What is the length of a^2?

Zanzabum

The law of cosines states that, if $\alpha$ is the angle between sides b and c,

$a^2 = b^2+c^2-2bc\cos(\alpha)$

So, plugging our values, we have

$a^2 = 16+16-2\cdot 4\cdot 4\cdot\cos\left(\dfrac{\pi}{4}\right)$

This is equal to

$a^2 = 32-32\cdot\dfrac{\sqrt{2}}{2} = 32-16\sqrt{2}$

The answer is 355 houses, but can someone tell me how please?

Ymorist [56]

So you do 20%*426 to get 85.2 then you would subtract 85.2 from 426 because they sold 20% more than last year. On top of that the answer isn't 355 it is 340.8.

Find the value of x 125 155

Solnce55 [7]

The value of x is 125 degrees from the given diagram

<h3>Lines and angle</h3>

Find the diagram attached

From the diagram, we can see that line l is parallel to line m, hence we can conclude that:

x = 125 degrees (The angles are corresponding angles)

Hence the value of x is 125 degrees from the given diagram
