Answer:

Area= 12 units squared, Perimeter= 16.12899

Step-by-step explanation:

AC= \sqrt{(4-0)^{2}+ (0+4)^{2}} = 4\sqrt{2}

AB= \sqrt{(0-4)^{2}+ (2-0)^{2} } = 2\sqrt{5}

BC= \sqrt{(0-0)^{2}+ (2+4)^{2} }= 6

So, perimeter= 4\sqrt{2} + 2\sqrt{5} +6= 16.12899

Area= \frac{1}{2}bh\\

        = \frac{1}{2}BC\sqrt{(4-0)^{2}+(0-0)^{2}  }

         = 12 units^{2}

podryga [215]

Answer:

1. U. 190

2.U. 155

3. U. 240

Step-by-step explanation:

Explanation: To find an angle of a triangle we add the angles we know about

EXAMPLE: 50 + 120. We need to find the third angle.

We know that Angles of triangles should add up to 360

So to find the third angle we add the angle we know about.

EXAMPLE: 50 + 120 = 170 then we Subtract the sum of a triangle *360*

EXAMPLE: 50 + 120 = 170

EXAMPLE: 170 - 360

EXAMPLE: = 190

That's how we find a third angle!

If this doesn't clarify how do to it enough just let me know and i can try to explain more in detail!

Hope this helps you!!!

Have a nice day!
