Given cos theta is equal to - 4/ 7 then we can conclude that theta is in the second and third quadrants. In this case, the other leg is equal to square root of (7^2 - 4^2 ) equal to square root of 33. In this case, sin theta can be equal to +- square root of 33 / 7 and tan theta is equal to +-square root of 33 / 4.
X=12. So this one says that it has 3 congruent sides so therefore it has to have 3 congruent angles. Here we have angle 2 and we have angle 60. Given the definition of triangle congruence, we can say that 60 is angle 2 and that the third angle is also 60 but it’s not relevant in this problem. So knowing that angle 2 is 4x+12 we solve for x by seeding that equal to 60 and then solving for x we get x=12. Hope this helps!!!!
Answer:
It would be <em>Graph D</em>
<em />
Step-by-step explanation:
It's graph D because according to the graph, it looks like the domain has 2 ranges since it made a vertical line. And as we know, vertical lines are not considered to be functional since a domain can't have more than one range.
Answer:
Step-by-step explanation:
<u>Volume of a cylinder:</u>
<u>Container A</u>
- r = 10 ft, h = 11 ft
- V = π*10²*11 = 1100π ft
<u>Container B</u>
- r = 7 ft, h = 19 ft
- V = π*7²*19 = 931π ft²
<u>After pump out the container A has the level of:</u>
<u>Level % in the container A:</u>
- 169π/1100π×100% = 15.4% rounded to the nearest tenth
Answer:
a. 38
b. 374
Step-by-step explanation:
a. 2 ft = 24 in + 5 in+ 9 in = 38 in
b. 4 yd = 144 + 6 yd = 216
144 + 216 + 8 + 6 = 374
Hope this helps!
