Answer:
x = 6
Step-by-step explanation:
Using this theorem to get the other angles of the triangle.
Angle at the vertex is equal to half of the angle at the intercepted arc
For the arc with angle 170degrees
Angle at the vertex = 1/2 * 170
Angle at the vertex = 85 degrees
For the arc with angle 90degrees
Angle at the vertex = 1/2 * 90
Angle at the vertex = 45 degrees
Taking the sum of the 3 angles and equating to 180
85 + 45 + 12x - 22 = 180
130-22+12x = 180
12x = 180 - 108
12x = 72
x = 72/12
x = 6
Hence the value of x is 6
Answer:
-18 + 6j
Step-by-step explanation:
3 * -6 is -18
3 * 2j is 6j

Answer:
583 calories for the 10 ounce box
Step-by-step explanation:
We can use proportions to solve this problem. Put calories over ounces
350 calories x calories
---------------- = ------------------
6 ounces 10 ounces
Using cross products
350*10 = 6x
3500=6x
Divide by 6
3500/6 = 6x/6
583.333333(repeating) =x
Round to the nearest calorie
583 calories for the 10 ounce box
So hmmm if we use the "intersecting chords theorem", the angle of 93°, is really 1/2 * (arcBC + arcAD)
thus
