Answer:
129.9 cm^2
Step-by-step explanation:
You can use the Law of Sines to find the hypotenuse. Because it's an equilateral triangle, it's the same value for the base. If you plug in the proper angles, being 90 degrees and 60 degrees because it's an equilateral triangle, the value of the base should be 17.32050808, or 17.32 if we're rounding. If you use the usual formula for finding the area of a triangle, b * h / 2 to get an answer of 129.9 cm^2. Hope this helps and isn't too confusing! There's a bunch of lessons on Khan Academy if you need more help!
This is a bit advanced for middle school, so we might be missing some information.
98.43 = 98 43/100 = (98 * 100 + 43) / 100 = 9843/100
98 is ur whole number....now look at ur numbers to the right of the decimal....what place is ur 3 in ? The 4 is in the tenths place....the 3 is in the hundredths place....so that makes it 43/100...now include ur whole number...so its 98 43/100...now if u don't want a mixed number...change it to an improper fraction which would be 9843/100.
