Answer:
Final answer is .
Step-by-step explanation:
Given problem is .
Now we need to simplify this problem.
Apply formula
so we get:
Hence final answer is .
The length can be found using the Pythagorean Theorem...
c^2=a^2+b^2 and in this case:
d^2=(dx^2)+(dy^2)
d^2=(3-7)^2+(12-9)^2
d^2=-4^2+3^2
d^2=16+9
d^2=25
d=5
So the length of AB=5 units.
Answer:
20/21
Step-by-step explanation:
tanC = opposite/adjacent = 20/21
Answer:
115
Step-by-step explanation:
since the angles are adjacent angles they equal 180
so 180-65= 115
x=115
