The total of all angles are 360 degrees for a parallelogram. One angle is 10 and the one opposite is also 10. B = 340/2=170 degrees
Answer:
n = 245/36
Step-by-step explanation:
Usually, these are solved in 2 steps:
- eliminate fractions by multiplying by the LCM of the denominators
- divide by the coefficient of the variable.
Doing that, we have ...
(49n)(36/49) = (49n)(5/n)
36n = 49·5 = 245 . . . . . simplify
n = 245/36 . . . . . divide by the coefficient of n
_____
Another way to do these is to rewrite the proportion with both sides inverted:
49/36 = n/5
Now, all you need to do is multiply by 5.
n = 5(49/36) = 245/36
__
Or, you can do both of the original steps at the same time:
(49n/36)(36/49) = (49n/36)(5/n)
n = (49·5)/36 = 245/36
Answer:
Step-by-step explanation:
<u>Finding the missing angle</u> :
- 22° + ∠R + 72° = 180°
- ∠R = 180° - 94°
- ∠R = 86°
<u>Applying the Law of Sines</u> :
<u>Substituting the known values</u> :
- sin 22° / P = sin 86° / 18
- P = sin 22° × 18 / sin 86°
- P = 0.374606593 × 18 / 0.99756405
- P = 6.76 cm
