Answer:
I suppose that the inequality is:
(1/11)*c > 9.
To solve this we need to isolate c in one side of the inequality.
To isolate it, we need to multiply both sides by 11, then we get:
11*(1/11)*c > 9*11
c > 9*11 = 99
c > 99.
To graph this, we will have an open dot at c = 99, and an arrow that points to the right direction.
The graph is shown below.
The value of .
The value of is 150°. ✅
We know that,
➡ 81° + = 180°
➡ = 180° -81°
➡ = 99°
Since an exterior angle of a triangle is equal to the sum of the two opposite interior angles, we have
=
+ 51°
Substituting the value of ''" in the above equation,
➪ = 99° + 51°
➪ = 150°
