Answer:
Yes
Step-by-step explanation:
To determine if this is a right triangle, use the pythagorean theorem and see if a^2 + b^2 is equal to c^2.
a^2 + b^2 = c^2
12^2 + 16^2 = 20^2
Evaluate the exponents.
144 + 256 = 400
Add them together.
400 = 400
Since a^2 and b^2 add up to equal c^2, this is a right triangle.

Answer:

Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
The exterior angle to interior angle is
exterior angle = 180° - 110° = 70°
Sum the exterior angles and equate to 360
x + 2x + 70 + 2x - 50 + x + 40 = 360 , that is
6x + 60 = 360 ( subtract 60 from both sides )
6x = 300 ( divide both sides by 6 )
x = 50
Then measure of exterior angles is
x = 50°
2x = 2 × 50 = 100°
x + 40 = 50 + 40 = 90°
2x - 50 = 2(50) - 50 = 100 - 50 = 50°
Answer:
5
Step-by-step explanation:
perpendicular slopes multiply to -1
lets say m is the missing slope
-1/5*m=-1 so m=5
