144 is a square of 12
Hope this helps!
16 3/4 + 12 3/4
16 +12 = 28
3/4 +3/4 = 1 1/2
28 + 1 1/2 = 29 1/2 hours total
Answer:

Step-by-step explanation:
As we know that the sum of opposite angles of a cyclic quadrilateral is 180.
The equation which is used to solve for the measure of angle P is y+w= 180.

Answer:
your best option is #2
Step-by-step explanation:
In a
let's say the unmentioned angle is Y
so a line is 180° thus Y+145°=180°
we can get y=35°
so a triangle has inside angle sum of 180 and this gives us
X-25°+X+35°=180°
2X=170°
X=85°
for b
we know the inner angles of any four sided figure is 360°
X-35°+2X-75°+X+X=360°
5X=450°
thus X=90°
