Assume that pi is approx. 3.14. Then 86.92 = approx. 27 2/3 times pi, or
86.92 is approx. equal to 83pi/3.
Answer:
Well a triangle itself is worth 180 degrees (Inteirior angles)
your given “a” “b” and you need to find c.
So you can subtract
A is 50
B is 55
So
<BCA= 180- 55-50
Is the answer (b)
The value of the expression 6·[(32-8)÷4+2]=48
Answer:
u•u = 17
u•v = 13
v•u = u•v = 17
v•u/u•u = 13/17
Step-by-step explanation:
Given 2 column matrices
u = [-1 4] and v = [7 5]
Note that when computing product, we will multiply component wise.
To compute u times u, we will take the dot product of both column matrix.
u•u = [-1 4] • [-1 4]
u•u = (-1)(-1) + (4)(4)
u•u = 1+16
u•u = 17
To compute u times v, we will take the dot product of column matrix u and column matrix v.
u•v = [-1 4] • [7 5]
u•v = (-1)(7) + (4)(5)
u•v = -7+20
u•v = 13
v•u/u•u can be gotten by simply substituting the resulting values.
v•u/u•u = 13/17
