I would say b hope this help ☺
Answer:
Step-by-step explanation:
do it your self
You use the formula below...,
Angle theta = cos^-1 [scalar product of the two vectors ÷ multiplication of their moduli]
For example...the angle between
(2i + 3j) and (4i + 5j)
Angle theta = cos^-1 [( 2(4) + 3(5))÷((square root of (2^2 + 3^2))×(square root of (4^2 + 5^2))
Angle theta = cos^-1 [ 23 ÷ ((square root of(13)) × (square root of (41)]
Angle theta = 5°
Answer:
18.18 /// 17.9982
Step-by-step explanation:
Multiplying by 100 means moving up the other number by two digits,
soo 100x (or 100(0.1818) is now 18.18
For the next one:
0. 1818
x 99
---------------
1.6362
16.3620
-------------
17.9982
I have no idea about that fraction part
