Answer:
<u>68.2°</u>
Step-by-step explanation:
This is a right triangle, so we can use SIN,COS,TAN to solve for the angle.
We want ∠YXZ
THe side opposite to the angle is given as 20
The side adjacent to the angle is given as 8
Which trig ratio relates "opposite" and "adjacent"??
It is Tan!!
Thus, we can write:
THis is the angle
<u>68.2°</u>
Answer:
Step 3, because the solution should also include all the values for x between the two given values
Step-by-step explanation:
step 1
we have
step 2
The graph in the given problem
step 3
Identify the solution when
so
using a graphing tool
The solution is the interval -----> [3,5]
see the attached figure
All real numbers greater than or equal to 3 and less than or equal to 5
therefore
The first step in which the student made an error is step 3
