Answer:
112
Step-by-step explanation:
So, we know that a triangle's sides must add up to have a sum of 180. If you add up your given lengths and you should get 47, not including x. Then if you look at the left side/the one without a given length and it should be identical to the 21, so you know that side is 21. So now add 21 to 47, you should get 68. Finally, you subtract 68 from 180 like this: 180-68, and it should equal 112. So you're answer is 112.
To find percentages, simply take the number that is not the "100%" number and divide it by the other number.
in this case,
52 / 130
complicated way of figuring it out if it makes more sense for you,
find how much is 1% of 130
130/100= 1.3
1% of 130 = 1.3
and then you just take 52 / 1.3

Answer:
Step-by-step explanation:
Areaof triangle = base * perpendicular height/2
= (8 * 4)/2
= 8*2 = 16 Sq.feet
Area= 1/2abSinC where a and b are sides and c is an angle. All sides= 6 inches, all angles= 60°
1/2x6x6xSin(60)= 9√3 in2
Answer:
i think the answer is (12*3.14 = 37.68cm is the circumference and 6^2*3.14 = 113.04cm2 is the area.)
