12 students are girls and 8 are boys.
Answer: 30 degrees
Step-by-step explanation:
All angles in a triangle add up to 180 degrees, so you can just write an equation to solve for the measure of angle F. Also, angle C is congruent to angle F because of CPCTC
124 + 26 + F = 180
150 + F = 180
F = 30
The measure of angle F is 30 degrees
Zero
There is no solution for these equations as there is no even one point of intersection between them
Answer:
Step-by-step explanation:
The given functions are:
and
We want to to find
Note that:
We substitute the functions to obtain:
We now substitute x=7, to get:
This implies that
