Work shown above! x = 7
To solve use the supplementary angle next to the unknown angle to find an expression for that unknown angle and use that with the expressions inside the triangle to set equal to 180 and solve for x.
hope this helps c:
The second graph I believe if not some else will try to help.
We are given a table showing the population and the area of different cities, A, B, C and D. To calculate the population density, divide the population over the total area of the city. The following statements are true:
<span>--The population density of City B is greater than that of City C.
--City D has the lowest population density of the four cities.
</span><span>--The population density for City B can be found using the ratio 48,592 : 26.</span><span>
