Step-by-step explanation:
A standard abacus is a traditional method used to perform basic mathematical calculations, such as addition, subtraction, multiplication and division.
There are 5 rods on a standard abacus.
The shape of the abacus has a series of vertical rods on which a number of beads are placed.
Each bead on a particular rod is considered as 1 unit, i.e. if there are three beads on a rod, the value of that rod is 3.
The last rod on an abacus is for the unit's place, the second last rod is for the ten's place, the third last rod is for the hundredth's place, the fourth last rod is for the thousandth's place and the fifth rod is for the ten thousandth's place.
The boat is roughly 654ft away from the base of the cliff.
Step-by-step explanation:
We have the angle 17°
The side opposite the angle is 200ft.
We want to find the length of the adjacent side.
So what equation has Opposite and Adjacent in it?
Tangent. (Remember SOH-CAH-TOA)
Tan = opp/adj
Tan(theta°) = opp/adj
Rearranging,
adj = opp/tan(theta°)
adj = 200/tan(17°)
adj = 654.17ft
And to double check you answer,
° = tan^-1(opp/adj)
° = tan%-1(200/654)
° = 17°
Since it easy u must equal the real # with the real # and the same for complex
so that 15+3*m =0 m=-5
-28 =4n n= -7
