Answer:
BD = 4.99 units
Step-by-step explanation:
Consider the triangle ABD only.
The angle formed is 31 degrees which occurs between two sides that are AD and BC.
We know that for a right angled triangle, the angle can always be taken as an angle between hypotenuse and base.
Thus, The perpendicular sides is then 3 units, where base is BD and Hypotenuse is AD
Using formula for tanθ
tanθ = Perpendicular/Base
tan31 = 3/BD
0.601 = 3/BD
BD = 3/0.601
BD = 4.99 units
Using the image I gave you, you don't need to solve for x.
So tan is opposite/adjacent
sin: opposite/hypotenuse
cos: adjacent/hypotenuse
Take theta and do: adjacent/hypotenuse which is cosine
cos theta = adjacent/hypotenuse
cos theta = 1.5/9
inverse cos = 1.5/9 and the answer is: 80.4 degrees

Hello!
To answer these, you can use prime factorization! Here is the first one:
1) 16x² and 8
Well we know the GCF will not have any "x" since only one of the numbers do. So, here is the prime factorization for each, excluding the "x", and I have also bolded the common numbers between the two:
16 8
2 · 8 2 · 4
2 · 4 2 · 2
2 · 2
Finally, multiply the common numbers (only once for each common number): 2 x 2 x 2= 8 is your GCF!!!
Hope this helps! :)
Answer:
163 degrees and 17 degrees
Step-by-step explanation:
x+y = 180
x-y = 146 then x = 146+y
substitute for x
146+y+y = 180
2y = 34
y = 17
x = 17+146 = 163
