Answer:
(2,-6) Brainliest???
Step-by-step explanation:
The green line is x=y
I recomend to use desmos for questions like this ;)
Answer:
C
Step-by-step explanation:
Use the sine ratio in the left, right triangle to find the common side to both triangles and the exact values
sin60° =
, cos45° =
, thus
sin60° =
=
=
( cross- multiply )
2 × opp = 21 ( divide both sides by 2 )
opp = ![\frac{21}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B21%7D%7B2%7D)
Now consider the right triangle on the right, using the cosine ratio
cos45° =
=
=
( cross- multiply )
x =
×
=
→ C
Answer:
![y=2\sqrt{3}\ units](https://tex.z-dn.net/?f=y%3D2%5Csqrt%7B3%7D%5C%20units)
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
<em>In the right triangle ABC</em>
-----> by a 45°-90°-45° triangle
so
![cos(45\°)=\frac{BC}{AB}](https://tex.z-dn.net/?f=cos%2845%5C%C2%B0%29%3D%5Cfrac%7BBC%7D%7BAB%7D)
![BC=ABcos(45\°)](https://tex.z-dn.net/?f=BC%3DABcos%2845%5C%C2%B0%29)
substitute the values
![BC=(2\sqrt{2})(\frac{\sqrt{2}}{2})=2\ units](https://tex.z-dn.net/?f=BC%3D%282%5Csqrt%7B2%7D%29%28%5Cfrac%7B%5Csqrt%7B2%7D%7D%7B2%7D%29%3D2%5C%20units)
<em>In the right triangle BCD</em>
![tan(60\°)=\frac{BD}{BC}](https://tex.z-dn.net/?f=tan%2860%5C%C2%B0%29%3D%5Cfrac%7BBD%7D%7BBC%7D)
substitute the values
![\sqrt{3} =\frac{y}{2}\\ \\ y=2\sqrt{3}\ units](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D%20%3D%5Cfrac%7By%7D%7B2%7D%5C%5C%20%5C%5C%20y%3D2%5Csqrt%7B3%7D%5C%20units)
Answer:
6
Step-by-step explanation:
<u>Area of sq:</u>
A = bh
A = (2)(2)
A = 4
<u>Area of triangle:</u>
A = 1/2bh
A = 1/2(2)(2)
A = 2
<u>Combined:</u>
4 + 2 = 6
