Answer:
(-3,-1)
Step-by-step explanation:
You can graph both of the points on desmos, and then look at the slope from p1 to the midpoint. so you can get the slope, and use it to get the p2. the slope is -4/6. So you get that answer.
Answer:
x=50
Step-by-step explanation:
40+65+25+x=180
Combine like terms
130+x=180
x=50
(triangles = 180)
Answer:
x=125°
Step-by-step explanation:
100° + 25° =125°
180°- 125° = 55°
and since adjacent angles on a line equal 180°
180° - 55° = 125°
x= 125°
First we must find area of a single square.
Meaning we divide total area of 80 centimetres squared by 5 since we have 5 squares in the shape.

Now from the picture we can see that the perimeter of shape is combined by 4 times 3 times the length of side of 1 square.
So we need to find side of 1 square.

As we stated before the formula for perimeter of this shape is:

The perimeter of shape is 48 centimetres.
Hope this helps.
