Which set of values could be the side lengths of a 30-60-90 triangle?
2 answers:
C). 6*6√2*12 is your answer.... i think
First of all, with 30-60-90 triangles, we know this ratio applies: Shortest side: middle length side: hypotenuse 1 : √3 : 2 Therefore, with this is mind, the only correct answer out of a,b,c and d is b. Finally, to further prove b is correct, let us check with the ratio: Ratio: 1 : √3 : 2 Option b 6 : 6√3 : 12 So as you can see, Option b matches with the 30-60-90 ratio. (Each ratio number can be divided by 6 to get the 30-60-90 ratio.) Hope this helps!

My present age - x Mom's age - 2x + 12 My age after 8 yrs - x +8 My mom's age after 8 years - 2x+20 Equation formed- 3(x+8)-20 = 2x+20 3x +24 -20 = 2x +20 x = 20-4 = 16 Therefore, my present age = x = 16 yrs And my mom's present age = 2x + 12 = 32+12 = 44
Answer:
D, because in between -3 and -2 is -2 1/2, and absolute values are not negative, so the answer is 2 1/2, or D
Answer:
6.4
Step-by-step explanation:
Using Pythagorean theorem (a^2+b^2=c^2), 4^2+5^2=41. The square root of 41 is 6.4.
