Since it is an isosceles trapezoid;
AB=CD which means;
5y-3=6y-17
get the variables to one side and you get:
-3=y-17
Then add 17 to both sides and
14=y
Therefore y=14 is your answer
Obtuse
The angle is larger than 90° but smaller than 180°
First you need to know that the internal angles of a triangle always equals 180°. Therefore:
15+45= 90°
Then since the angles should equal 180, you do:
180-90=90
So the missing angle equals 90°
the answers are clear if you use priority and equation rules.
- q=11
- u=2
- a=13
- l=8
- s=12
