Answer:
Step-by-step explanation:
There are 2 similar triangles.
EDA and CBA
From that we can get the following proportion.
ED / CB = AD / AB
Filling in the letters we get
6/x = (4 + 3)/3 Combine
6/x = 7/3 Cross Multiply
7x =6*3
7x = 18 Divide by 7
x = 2.57

Answer:
3,2 i think sorry if im wrong
Answer:
x = - 3, y = 6
Step-by-step explanation:
For the 2 sides to be equal then the coefficients of the imaginary terms and the real terms must be equal.
Given
- 3 + yi = x + 6i , then
x = - 3 and y = 6
Answer:
See below in bold.
Step-by-step explanation:
Ship's vector:
Horizontal component = 30 cos 30 = 25.98.
Vertical component = 30 sin(-30) = -15.
So it is <25.98, -15).
The current's vector:
Horizontal component = 5 sin 20 = 1.71.
Vertical component = 5 cos 20 = 4.7.
So it is <1.71, 4.7>.
