Given a 30-60-90 triangle whose shortest leg is 3 centimeters what is the length of the hypotenuse
1 answer:
the lenght of the hypotenuse is determined either by taking into account sin 30, respectively sin60 and/or cos60, respectively cos30.
Sin 30 = cos60=1/2
the opposite line to the 30 degrees angle is (in this case) called "the shortest leg"
Therefore the value of the hypothenuse is 30×2=60mm

Answer:
aₙ=(-2)ⁿ*2.
Step-by-step explanation:
1) -4*(-2)=8; 8*(-2)=-16; -16*(-2)=32, ...
2) the required equation is:
aₙ=(-1)ⁿ*2ⁿ*2; ⇒ aₙ=(-2)ⁿ*2 or aₙ=(-1)ⁿ*2ⁿ⁺¹.
