9 because it take 3 to fill 1/3 do 3 times 3 and its nine
M = y2-y1 / x2-x1
= 2-1 / 1-2
= 1 / -1
= -1
Answer:
Congruent, SSS
Step-by-step explanation:
The dashes on the sides of the triangles represent that the corresponding lengths of the triangles are equal in length. Since it is given that all corresponding lengths of the triangles are equivalent, the triangles are congruent by the SSS (side, side, side) test.

Answer:
135
Step-by-step explanation:
I solved it step by step in picture. U can have a look. ✌️
This is a triangle
To find the area, count the side (which is 5)
You can see that the peak opposite of the side is 7 units in length, that is the height
The formula for the area of the triangle is
A = (b * h)/2
b = 5
h = 7
A = (5 * 7)/2
A = 35/2
A = 17.5
Hope this helps
