Since the triangle DEF is an equilateral triangle and x is the height of this triangle, we can use the following formula for the height of an equilateral triangle:
Where 'l' is the length of the triangle side.
So, using l = 13, we have:
So the value of x is 11.2
Hello.
In your question, we can see that the points Q, P, and R can be assumed that they are in a straight line, meaning that the angle measures will add up to 180 (think of half a circle, which is 360 degrees).
This means that every angle added up will add up to 180 degrees.
Meaning we can set up the below equation:
After finding , we can plug it back in to each expression for each angle measure.
∠QPS =
∠SPT =
∠TPR =
Hope this helps!
