Answer:
x =3.6666.... This can be rounded to 3.7
Step-by-step explanation:
-x + 4x + 1 = x+12 -x
3x +1 -1 = 12 -1
3x / 3 = 11 /3
3.6666...
Hope this helps! :)
Answer:
It will be 6:10
Step-by-step explanation:
Answer:
<em>The <u>exterior angle inequality theorem</u> states that the measure of any exterior angle of a triangle is greater than </em><em>t</em><em>h</em><em>e</em><em> </em><em>measure</em><em> </em><em>of</em><em> </em><em>either of the opposite interior angles</em><em>.</em>
<u>EXAMPLES :-</u>
1.
suppose there's an isosceles triangle with exterior angle 150°.
so it's interior angle will be 30°
lets say that the interior opposite angles are equal and let them be equal to x.
sum if all angle sin a triangle = 180°
x + x + 30 = 180
2x = 150
x = 75.
thus we see the theorem states above is proved.
2.
let's say we have a triangle with exterior angle 60°
and one of it's interior opposite angle is said to be 40°.
one we can find out ourselves by subtracting the exterior angle from 180.
and sum of all angles = 180
asumming the unknown angle to be x.
120 + 40 + x = 180
x = 180 - 160
x = 20
hence the exterior angle inequality theorem has been proved once again.
Answer:
Correct choice is 4, f(6) = 15
Step-by-step explanation:
f(6) means x = 6. If you look at the piecewise function, x = 6 meets the criteria for the second equation which is just 15. You need the first equation ONLY if x is less than 4.
