Step-by-step explanation:
A line segment has two endpoints and a ray has one endpoint....
so it is a line segment.
Complex numbers are numbers that can be expressed in the form a + bi, a and b are real numbers whereas I is the imaginary unit that satisfies the equation I^= -1. In this expression, a is referred as the real part of the complex number, b is referred as the imaginary part.
When finding the third side of a scalene triangle, use Law of Cosine with its formula
c^2 = A^2+B^2 - 2AB(cosC)
Now, you just have to input all your data in the formula,
c^2 = 6^2+11^2 - 2(6)(11)(cos40degrees)
c^2 = 36+121 - 2(6)(11)(cos40degrees)
c^2 = 36+121 - 2(6)(11)(0.77)
c^2 = 157 - 101.12
c^2 = 55.88
c = square root of 55.88
c = 7.48 ft
Length of EF is 7.48 ft
