Points M and N are two of the vertices of a right triangle. They are the endpoints of the hypotenuse MN¯¯¯¯¯¯¯ of the triangle.
The third vertex lies in the fourth quadrant. Plot a point at the location of the third vertex.
2 answers:
The triangle in the image below shows the RED line and 2 GREEN lines.
<em>The RED line is the Hypotenuse MN</em>
<em>The two GREEN lines connect to form a right triangle to complete this triangle.</em>
Point (5, -2) is the point on the fourth quadrant that is the third vertex of the right triangle.
ANSWER: (5,-2) is the 3rd vertex of the right triangle (graph shown)

Bob need to paint 205 square feet.
Solution:
Length of the door = 7 ft
Breadth of the door = 5 ft
Area of the door = length × breadth
= 7 × 5
= 35
Area of the door = 35 ft²
The given image is a trapezoid.
Top base = 12 ft
Bottom base = 20 ft
Area of the trapezoid =
= 240
Area of the trapezoid = 240 ft²
Surface area to paint = Area of the trapezoid – Area of the door
= 240 ft² – 35 ft²
= 205 ft²
Hence Bob need to paint 205 square feet.
