Answer: 296 degrees
Step-by-step explanation:
Arc PRT is just the entire circumference - arc PT.
Since the 64 degree angle is a central angle, arc PT measures 64 degrees.
So arc PRT = 360 degree - 64 degree = 296 degrees.
At first find the area of rectangle:
(x + 4)*(x + 1) = x^2 + 5x + 4
Then find the area of triangle:

Then you must do like this
Area of rectangle - Area of triangle = Area of the shaded
x^2+5x+4 - (

)
Answer:
B
Step-by-step explanation:
So the ratios are 4 to 5 to 5 to 8 to 9 to 9
that means that the first 2 sides can be simplified to 4 to 5
therefor the whle sum is all the units added up
4+5+5+8+9+9=40
720=40 units
divide by 40
18=1 unit
solve for each unit
we have
4 units
5 units
8 units
9 units
4 times 18=72
5 times 18=90
8 times 18=144
9 times 18=152
the angles are
72,90,90,144,152,152
