Right ankle is exactly 90 degrees, while obtuse is more than, and acute is less than
Lets say the base is x and the height is y. The new base would be 1.2x and the new height would be 1.3y
Area of a triangle is base times height divided by 2:
1.2x*1.3y/2 = (1.2*1.3 + x*y)/2 = 1.56xy/2 = 0.78xy = 78% of xy
But a normal area would be 50% of xy
78% - 50% = 38%
ANSWER: 38% increase
The 5 and 10 min cross. 10
<span>The 5 min returns. 15 </span>
<span>The 20 and 25 min cross 40 </span>
<span>The 10 min comes back 50 </span>
<span>The 5 and 10 min cross again in60 Mins</span>
The graph is shown in the attached image.
Well, you could easily type that into a calculator, but the answer would be 0.04347826, but when you say it as an answer you say the answer up to the hundredths place, which would be 0.043. =)
