Answer:
a = 72° b = 88°
Step-by-step explanation:
We know in the cyclic quadrilateral opposite angles are supplementary so
a + 108° = 180° { being opposite angles of cyclic quadrilateral }
a = 180° - 108°
a = 72°
b + 92° = 180° { being opposite angles of cyclic quadrilateral }
b = 180° - 92°
b = 88°
Answer:
Here are my answers
hope this helps
Step-by-step explanation:
1. isosceles triangle
2. 3x + 15 = 90 x = 25
x + 25 = 90 x = 65
x + 55 = 90 x = 35
3. The size for DAB is 84
My reasoning is I went from one angle to another by subtracting 180 from my answers. For example angle 132 is supplementary to the missing angle next to it. I subtract 180 from 132 and get 48. That already solves the 2 equivalent angles in the triangle so I have 48+48+x = 180 because a full triangle equals 180. I get x = 84 then I do the same thing I did with angle 132. Angle 84 is supplementary to the missing angle next to it. I subtract 84 from 180 and get 96 then go diagonal from angle C (which is 96) to angle A. Those are supplementary so I subtract 96 from 180 and get 84.
Answer:
range
Step-by-step explanation:
Mean- add all the numbers up and divide by how many numbers you added
65/8 =8.125
Range- Find the largest number and subtract the smallest number from it
20-3 =17
Median- put the numbers in order from least to greatest and find the number/s in the middle
3,3,4,5,6,8,16,20- since there are an even amount of numbers add the two in the middle and divide by 2
5+6=11 11/2 = 5.5
Mode- the number that repeats the most
3 repeats the most
20.15625 is the answer to your question if you would like the method you move the percentage two decimal places and multiply.
