Answer: next time I encouage the use of use a trig calculator - or look it up on khan adademy, specificly trig sine cosine and tangent. plz and thankyou, HK=14.553---
Step-by-step explanation:
aside from the fact that this is multiple questions i will awnser the second wich is about triange "HJK" its actualy really easy -use a trig clalculator I like this one https://www.calculator.net/triangle-calculator.html?vc=52&vx=&vy=&va=&vz=14&vb=73&angleunits=d&x=62&y=28 ---but its your choice otherwise look up sin cos and tan on khan academy, wich is free. but for now i beleive this is what you need, i inserted the image subsitute the abc values for hjk and you got all the stats! (khan gives a better explanation than me on this!

Step-by-step explanation:
Answer: See the graph attached.
Step-by-step explanation:
The standard form of a quadratic function is:
Where (h,k) is the vertex of the parabola.
If is negative, then the parabola opens down.
Then, for the function:
You can identify:
Then the vertex of the parabola is at (2,4)
Note that , therefore the parabola opens down.
Find the intersection with the x-axis. Substitute and solve for x:
Knowing that the vertex is at (2,4), the parabola opens down and it intersects the x-axis at x=0 and x=4, you can graph the function, as you observe in the figure attached.
