thank you for hurrying here is the very last one Explain how you would find the perimeter of this triangle.
Lena [83]

Step-by-step explanation:

Use the method of TOA CAH SOH.

tan(51.3) =  \frac{opp}{adj}  \\  \tan(51.3)  =  \frac{u}{4}  \\ u = 4 \tan(51.3)

cos(51.3)  =  \frac{adj}{hypo}  \\  \cos(51.3)  =  \frac{4}{v}  \\ v \cos(51.3)  = 4 \\ v =  \frac{4}{ \cos(51.3) }

Perimeter of triangle = Sum of all sides =

u \:  +  \: v + 4

(((QUICK QUESTION-WILL GIVE BRAINLYEST)))
svetoff [14.1K]

Given:

Point (7,12) is rotated 1260° counterclockwise about the origin.

To find:

The  x-coordinate of the point after this rotation.

Solution:

If a point is rotated 360 degrees then its coordinates remains unchanged.

If a point is rotated 180 counterclockwise about the origin degrees, then

(x,y)\to (-x,-y)

We know that,

1260^\circ=1080^\circ+180^\circ

1260^\circ=3\times 360^\circ+180^\circ

After 3\times 360^\circ rotation the coordinates of points remains same, i.e., (7,12). So, after that (7,12) is rotated 180° counterclockwise about the origin.

(7,12)\to (-7,-12)

The point (7,12) becomes (-7,-12) after rotation of  1260° counterclockwise about the origin.

Therefore, the x-coordinate of the required point is -7.
