-3(5-9v)=25+7v
-15+27v=25+7v
+15 +15
27v=40+7v
-7v -7v
-20v=40
divide 40 by -20
v=-2
The angle between u = (-2,-5) and v = (5,2) is 134 degrees approximately.
<u>Solution:</u>
Given, two vectors are u = (-2, -5) and v = (5, 2)
We have to find the angle between two vectors.
We know that,

where
is angle between vectors a and b




Hence, the angle between given two vectors is 134 degrees approximately.
Answer: 12.5
Step-by-step explanation:
the scale drawing is : 1cm..................80 m
if the width is ? ..................1000m
the width on the scale drawing it will be 1000/80=12.5
