Using the pythagorean theorem: c^2 = a^2 + b^2
c = 12 feet
a = 3 feet
b = x feet
12^2 = 3^2 + x^2
144 = 9 + x^2
144 - 9 = x^2
135 = x^2
x = 11.6 feet
Therefore, the answer is B.
Answer:
ST is longest
Step-by-step explanation:
- <em>Theorem: </em>
- <em>If one side of a triangle is longer than another side, then the angle opposite the longer side will be larger than the angle opposite the shorter side</em>
The values of the angles are:
- ∠S= 50°,
- ∠T= 60°,
- ∠R= 180°- (50°+60°)= 180° - 110° = 70°
Since ∠R is the largest angle, the side ST is longest
The parenthesis should be placed in 310-20/2 x (5 + 13) =130
200 times 40000 is 8000000.

8000000
The answer is 11/12 , when getting the answer you have to get common denominator so you’d do 1/4 X 3 and you’ll get 3/12 then after all you do is add the numerator , hope this helped !
