Answer:

-\frac{110}{9}

Step-by-step explanation:

Given expression is (-2)^{3} +4/(-15+9)(3)-4

Let us perform the operations inside the parentheses first.

-8 +4/(-6)(3)-4

-8 +4/(-18)-4

-8-\frac{4}{18} -4

=-12-\frac{4}{18}

=-12-\frac{2}{9}

=-\frac{110}{9}

If cos theta =12/13.find 1+cot theta
hammer [34]

Answer:

17/5

Step-by-step explanation:

If cosθ = 12/13, find (1+cotθ)

As shown in the diagram attached,

Cotθ = 1/tanθ = adjacent/opposite

From the diagram attached,

cotθ = 12/a................... Equation 1

But we can find the value of a by using  pythagoras theorem

13² = 12²+a²

169 = 144+a²

a² = 169-144

a² = 25

a = √25

a = 5.

Substitute the value of a into equation 1

Therefore,

cotθ = 12/5

(1+cotθ) =(12/5)+1 = (5+12)/5

(1+cotθ) = 17/5
