Answer:
3^7
Step-by-step explanation:
We know that and since it's multiplied by
which is the same thing as
we know that
.
Given:
The inequality is
To find:
The inequality that solution describes all the solutions to the given inequality.
Solution:
We have,
Using distributive property, we get
Divide both sides by 3.
It can be written as
Therefore, the value of x is greater than 3. So, the required inequality is either or
.
1. Given any triangle ABC with sides BC=a, AC=b and AB=c, the following are true :
i) the larger the angle, the larger the side in front of it, and the other way around as well. (Sine Law) Let a=20 in, then the largest angle is angle A.
ii) Given the measures of the sides of a triangle. Then the cosines of any of the angles can be found by the following formula:
2.
3. m(A) = Arccos(-0.641)≈130°,
4. Remark: We calculate Arccos with a scientific calculator or computer software unless it is one of the well known values, ex Arccos(0.5)=60°, Arccos(-0.5)=120° etc
