You can figure out angle b by solving for angle a first. Since angle a and 117 degrees are on the same line, both angles equal to 180 degrees. Subtract 117 from 180 and you get 63 degrees. So that means you have two angles of the triangle, 81 degrees and 63 degrees. Since a triangle is equal to 180 degrees, add both 81 degrees and 63 degrees then subtract the sum by 180. This would give you the answer of 36 which is angle b.

Answer:

x = $11400

Step-by-step explanation:

Naomi is paid $190 per week plus 5.5% of her total sales in dollars, x, which can be represented by g ( x ) = 190 + 0.055 x.

And Josiah is paid $475 per week plus 3% of his total sales in dollars, x, which can be represented by f ( x ) = 475 + 0.03 x

Let the weekly pat for them are equal.

Then, g(x) = f(x)

⇒ 190 + 0.055 x = 475 + 0.03 x

⇒ 0.025 x = 285

⇒ x = $11400

Therefore, for the value of x = $11400, that will make their weekly pay the same. (Answer)
