The triangle shown is a right triangle shown by the little square inside of it.
Area of a triangle is 1/2 x height x base
Rotating the shown triangle so the square is at a bottom corner the height is 6 and the base is 6
Area = 1/2 x 6 x 6 = 18 square cm
Answer:
18.84
Step-by-step explanation:
The formula for length of the circle is =
Therefore
Therefore the Arc length =37.68/2
=18.84
All I know is that m=9 and p=1
Sine (46) = IG / 11
IG = sine (46) * 11
IG = 0.71934 * 11

The answer is A. Angles of a triangle will always add up to 180. If you add up 70+67+57 you are left with 194, which is 14 more than 180. Because we need to be at 180, we can assume that x is a negative number. If we say x is negative 7 we are able to takeaway 7 from 67 and 57. After this, we see that the sum of our angles is 50+60+70=180. Therefore, x=-7 in this situation and angle A is equal to 60. The answer is A.
