Vladimir79 [104]

Answer:

<h2>9.656cm</h2>

Step-by-step explanation:

Applying  SOH CAH TOA

The opposite to the angle 44° is the height

let the height be x meters

The distance from the both to the lighthouse is 110 meters which is the adjacent

Applying Tan ∅= opp/adj

The equation used to find the height is Tan ∅= opp/adj

Tan (44)=\frac{x}{110} \\\0.9656= \frac{x}{110} \\\\0.9656*10= x\\9.656=x\\x= 9.65cm

The height is 9.65cm

OlgaM077 [116]
First term a1=10 & r=0.5 & n=4

The formula to find the term =a(n) = a(1)*(r)^(n-1)

a(4th)=10*(0.5)^3 =1.25


proof:


a1=10

a2=10*0.5=5

a3= 5*0.5 = 2.5

a4= 2.5*0.5=1.25
