Answer:
See explanation
Step-by-step explanation:
Given
--- scale factor
See attachment for triangles
Solving (a): The relationship between the angles of both triangles
The sine of an angle is:
By comparing the above to
Using Pythagoras theorem:
So, we have:
Collect like terms
Take square roots
--- approximated
For angle X, we have:
So, the relationship between both triangles are:
Solving (b): How to find CB and AB
In (a), we have:
For angle X, we have:
This implies that:
is dilated by scale factor 2 to give
So, CB and AB of are:
She ran for 2 and a half hours
12.5/5=2.5
Answer:
The slope is b. 10, and the slope represents a. The total cost of the membership.
Step-by-step explanation:
It goes up by 10 every month that goes by, and the graph is labeled total cost of gym membership.
the solution of inequality is
Step-by-step explanation:
We need to draw graph of the solution to inequality
First we will solve the inequality to find value of x
Solving the inequality:
Adding 7 on both sides
Divide both sides by -3 and reverse the inequality
The graph is attached in the figure below.
So, the solution of inequality is
