Answer:
13ab
Step-by-step explanation:
When you add the 5 and 9 it will give you 14 but you still have to subtract the 1ab(there is a 1 in front of variables that don't have a visible number.) So it will be 13 a b.
Answer:
145°
Step-by-step explanation:
< 6 + <2 = 180° {being linear pair }
70° + < 2 = 180°
< 2 = 180° - 70°
< 2 = 110°
Now
< 4 = < 1 + < 2 (exterior angle of a triangle is equal to the sum of two opposite interior angles)
<4 = 35° + 110°
= 145°
Hope it will help :)
Area of the square: 29.0
Step-by-step explanation:
The area of a square is given by
where
L is the length of the side of the square
The sides of a square all have the same length, so here we just need to find the length of one side.
The length of the side of the square here is the distance between two vertices, which can be calculated as
where
are the coordinates of the 1st vertex
are the coordinates of the 2nd vertex
By taking the two vertices (3,6) and (1,1), we find
Therefore, the area of the square is:
