Create a word problem using 30+2d as the answer
Tanzania [10]

Answer:

Sonya pays a flat fee of $30 for her phone bill and pays $2 per gigabyte she uses per month. Put Sonya's bill as an equation with <em>d</em> being how many gigabytes she uses per month.

Step-by-step explanation:

We get the flat fee of $30 from "30 + 2d" and the $2 per gigabyte from "30 + 2d" and since we want to find out Sonya's total bill, that's where the + in "30 + 2d" comes from. We want the variable to be <em>d</em> therefore <em>d</em> is how many gigabytes she uses per month.

I need help with help on the one with the pink circle
podryga [215]

Answer:

15°

Step-by-step explanation:

The line in the middle of the triangle divides it into two triangles.  These two triangles are equal.  You can see this because the given angle (90°) is equal for both sides, and the bottom sides (23) are also equal to each other.  

Since the triangles are equal, this means that the given angle of 75° also applies to the other side.  The total degrees a triangle can have is 180°.  Use the given angles to solve for the unknown angle.

75° + 90° + x = 180°

165° + x = 180°

x = 15°

The angle measure will be 15°.
