Hey there!
If you look at the image you've been given, you can see that there are four complete repeats of each individual angle. What I mean by this is that you can take that angle, lay it on top of three other angles you've been shown, and it will be the exact same. These are corresponding angles.
An example would be (1, 9, 3, and 11). Any of these are the exact same angle, placement and degree included, as the others. The other examples in this problem would be (2, 10, 4, and 12), (6, 14, 8, and 16), and (5, 13, 7, and 15).
Your answer will be C, angle 3 and angle 11.
Hope this helped you out! :-)
Answer:
92⁰
Step-by-step explanation:
a = 35⁰ ( vertically opposite )
b = 53⁰ (vertically opposite )
a + b + x = 180⁰ (Angle sum property of triangle)
35⁰ + 53⁰ + x = 180⁰
x = 180⁰ - 88⁰
x = 92⁰
Answer: 52.77876 in
Explanation: C=2πr=2·π·8.4≈52.77876 in
The mistake she made was timesing the 6 by the -7.5 as there is no x after the 6
Therefore:
-3.8(-7.5) +6
28.5+6 =34.5
One half life 1000 mg to 1000/2 =500 mg
One half life 500 mg to 500/2 = 250 mg
One half life 250 mg to 250/2 = 125 mg
