Answer:
b. 57
Step-by-step explanation:
AO and BO are both radii, so they're congruent, and it's an isosceles triangle. Therefore, angle A and angle B must be congruent, so we can write the equation x+x+66=180, solving for x gives us 57
The possible outcomes where the red die shows a 3 are: (red, blue) = (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6).
You will need to know that the sum of "two complementary angles" is 90
therefore
Let x = one angle
then
90-x = second angle
.
Now, we construct our equation based on the sentence:
"The sum of the measures of two complementary angles exceeds the difference of their measures by 86°."
x + 90-x = x-(90-x)+86
90 = x-90+x+86
90 = 2x-90+86
90 = 2x-4
94 = 2x
47 degrees = x (first angle)
.
Second angle:
90-x = 90-47 = 43 degrees (second angle) hope it helps
Answer:
For there to be a greatest return on investment, you will be looking at which line has a higher value at Year 5 compared to Year 1, irregardless of the ups and downs in between. It can be observed that only the green line and the purple line shows an overall increase in Year 1 and Year 5. Hence the answer would be A&D and Peer comms (I can't really see the picture properly)
