Answer:
Because the sum of the interior angles of a triangle is 180,
X=180-(65+35)
X=180-100=80
Answer:
choice B should be right
Step-by-step explanation:
Given the expression below

To find n
Open the brackets

Collect like terms

Since, the sides are not equal,
Hence, there is no solution
magnitude = sqrt(6^2+4^2)
= sqrt ( 36+16)
=sqrt (52) = 7.2
angle = tan^-1(6/4) = 56 degrees
