105 degrees is from a b to d and a b to c is 75 and 105 - 75 =30.
Answer:
-69 +92 i (here 'i' is imaginary value)
Step-by-step explanation:
step:-
Given (3-4 i)(-2-21)
on multiplication, we get
(3-4 i)(-2-21) = 3(-2) -3(21) - 4 i (-2) +4 i(21)
= -6 -63 + 8 i +84 i
= -69 +92 i
-69 + 92 i is a complex number.
real part x = -69
imaginary part y = 92
Maybe it’s -2(46+13) or -92-26v
Answer:
13 degrees
Step-by-step explanation:
Triangles have to equal to 180 degrees
To solve this, let's first convert the equation to standard form:
9 + (x/4) = 12
Now, let's solve for x:
9 + (x/4) = 12
9 + (x/4) - 9 = 12 - 9
x/4 = 3
x/4 * 4 = 3 * 4
x = 12
