Answer:
WX = 8 mm
Step-by-step explanation:
To be able to solve for WX, we need to first find the size of angle
.
We use the law of sines in the blue triangle to do such:

Now we can use this value in the larger right angle triangle where WX is the opposite side to angle
, and the 20 mm side is the hypotenuse:

which rounded to the nearest integer gives
WX = 8 mm
Y=a(x-h)^2+k
-5=a(1-0)^2+2
-5=a+2
-3=a
y=-3x^2+2
Answer
Theair no error because theair the answer ni the steps And all its ok
Step-by-step explanation:
W=367 because 210+157 is 367 so 367 minus 157 would be 210 so I think w=367. The equation is just written backwards
<span>The exact solution of cos (17</span>π<span>/6) is as follows:
First change the angle into degrees.
17(</span>π/6) (180°/π) = 510°
Then we calculate the cosine of the angle above and it as follows:
cos 510° = -(√3)/2
Hope this answers the question. Have a nice day.
