I used google calculator just search triangle length calculator
11 2/3, I think. 2*3 + 1 = 7 & 7/3*5/1 (where you do straight multiplication) you get 35/3 which simplifies to 11 2/3. Hope this helped, but um what is the weight measurement or is that not mentioned?
Angle R can be solved using the inverse sine button on a calculator. Sine is y/r so opposite leg over the hypotenuse. For r, the opposite leg is 5cm and the hypotenuse is 13. The inverse sin button looks like sin^-1. Punch that in the calculator (make sure in degree mode). Punch the inverse sin and then 5/13 and you should get 22.62°
Answer:
B maybe? that doesnt equal any
Step-by-step explanation:
f(x)=3x^2+6x
f(2)=3(2)^2+6(2)
f(2)=3(4)+12
f(2)=12+12
f(2)=24
