Answer:
Measure of the smallest angle.
LA= n+18 degrees= 10 degrees+ 18 degrees= degrees
The answer is 28 degrees

Answer:
x=4
Step-by-step explanation:
C+E=180
14x-8+132=180
14x=180-132+8
14x=56
x=4
Answer:
See proof below
Step-by-step explanation:
We will use properties of inequalities during the proof.
Let
. then we have that
. Hence, it makes sense to define the positive number delta as
(the inequality guarantees that these numbers are positive).
Intuitively, delta is the shortest distance from y to the endpoints of the interval. Now, we claim that
, and if we prove this, we are done. To prove it, let
, then
. First,
then
hence
On the other hand,
then
hence
. Combining the inequalities, we have that
, therefore
as required.
Cos(x°) = (√3)/2
cos⁻¹[(√3)/2] = x°, that means x° = 30°
