Answer:
JMK = 54
JKH = 126
HLK = 90
HJL = 27
LHK = 63
JLK = 27
Step-by-step explanation:
Just use 180 for total angles in each triangle. Vertical angles mean the opposite to 126 is 126 and the other two that make up the inner vertices are (360- 126*2)/2 = 54
So, 126, `16, 54 , 54 are the inner angles in the circle. Just go from there.
Answer:
0.9950 to the nearest ten thousandth.
Step-by-step explanation:
We use the identity sin^2 t = 1 - cos^2 t
sin^2 t = 1 - (0.1)^2
= 0.99
So sin t = 0.9950 (answer).
We can see that window is in shape of rectangle. So the length of the required wood to frame window is equal to the perimeter of rectangle.
SO the length of rectangular window is

feet.
Width of the rectangular window is =

feet.
In general parameter of rectangle is =

So the parameter of window is =

So the required length of wood to frame window is = 28.834 feet
