Answer:
8
Step-by-step explanation:
The interior angles of a triangle always add up to 180°.
As QE=ED=QD
so, ∠Q=∠E=∠D=180°/3=60°
As, ∠D=5x+20
60=5x+20
5x=40
x=8
Hope, this helps you.
You set up the equation like this:
T/45+T/53=1
You find the least common factor of 53 and 45 and times both sides so you end up with this:
53T+45T= least common factor
Then add up 53T and 45T.
98T= least common factor
Then divide 98 from both sides. That will be your answer.
Sorry I didn't have enough time to find the least common factor but it is a number that they both go into. I would check to make sure I'm correct. I hope this helps!
Subtract 7 from 4 and Mark it on the grid, then, in order to reflect it, mark the same line in the (-,+) corner. (new coordinates are (-5,7)(-5,3)
