"An angle that forms a linear pair with one of the interior angle the triangle" is the best definition of an exterior angle of a triangle.
<u>Option: C</u>
<u>Explanation:</u>
When to the sum of the inward angles opposite outer angle of a triangle the sum of the inward angles opposite is equivalent thus understood as exterior angle of a triangle.
The Triangle outer angle theorem for more about is if at each vertex the equivalent angle is drawn, the outer angles always add up to 360°. In reality, this is valid for any convex polygon, not just triangles.
In the most easiest pattern , since any angle of triangle equivalent is 60′, the outer angle would be 120′. Therefore all exterior angles sum is:
120 + 120 + 120 = 360°.
6-3/4x+1/3=1/2x+5
6+1/3-5=1/2x+3/4x
4/3=5/4x
x=16/15
Answer:
6
Step-by-step explanation:
g(x) = x2 - 4
g(5)= 5(2) - 4
g(5)= 10 - 4
g(5)= 6
Have a great day
Answer:
3.4
Step-by-step explanation:
0.5x+4.2=5.9
Subtract 4.2 from both sides:
0.5x=1.7
Divide both sides by 0.5:
x=3.4
Hope this helps!
Answer:
x = 6
Step-by-step explanation:
Given
+ 4 = 7 ( subtract 4 from both sides )
= 3 ( square both sides )
2x - 3 = 3² = 9 ( add 3 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
