Answer:
7.26 to the nearest hundredth.
Step-by-step explanation:
The ratio opp/hyp is the sine of the angle.
So if we let the opposite side = x then
3.5/ 8.2 = x /17
x = (3.5 * 17) / 8.2
= 7.256
At the seventh meeting there would be 20 members. If you think about the question carefully there were 12 members at the first meeting, then they skipped 6 meetings, with each meeting being skipped or not written down they added 1 member, so therefore you would add 2 members for the next 2 meetings. making 20 members.
Hope this helps! :)
Lets try it this way. 3 numbers sum is equal to 81, thus A+B+C = 81. Now lets go to the next portion of the question.
The second number is 4 times the first.
B = 4A
The third number is 3 more than the first
C = 3+A
since we have everything in terms of A lets solve for A.
A+ 4A+ (3+A) = 81
do some simple math to find A.
A+4A + 3 + A = 81.
6A + 3 = 81
6A = 81 -3
6A = 78
A = 13
Now we got A lets solve for B and C.
B = 4A
B = 4(13)
B = 52
C = 3+A
C = 3+13
C = 16
Now lets check our answer
A+B+C = 81
13+52+16 = 81
Answer:
Here are some formulas and some info to get you started:
Step-by-step explanation:
Parallelogram:
Area = Base · Height
Triangle:
Area = 1/2 · Base · Height
Know that the height is the vertical dotted line. Also know that the horizontal dotted line attached to the base is not actually part of the base.
If you need any more help let me know, and good luck!
I'm assuming the question is referring to a regular pentagon where all the sides and angles are equal, because otherwise, I would need more information (such as lengths of sides, meausures of angle, diagram, etc) to be able to solve this.
180(n-2)
n = 5 because a pentagon has 5 sides
5 - 2 = 3
180 * 3 = 540
divide 540 by 5 (again, because a pentagon has 5 sides)
540 ÷ 5 = 108
The sum of all the interior angles together is 540 degrees, and the measure of just one of them is 108 degrees
