Step-by-step explanation:

Given

The question is illustrated with the attached image

Required

Find $\theta$

To do this, we use sine formula

i.e.

$\sin(\theta) = \frac{Opposite}{Hypotenuse}$

So, we have:

$\sin(\theta) = \frac{10.8}{16.6}$

$\sin(\theta) = 0.6506$

Take arc sin

$\theta = \sin^{-1}(0.6506)$

$\theta = 40.59^\circ$

Three consecutive integers sum to 6. What is the least of these integers?

dexar [7]

Answer:

The least of the three integers is 1.

Step-by-step explanation:

Hi there!

Let x be equal to the least of these integers.

Let x+1 and x+2 be the next consecutive integers.

We're given that these integers have a sum os 6.

We can use these to construct an equation:

$(x)+(x+1)+(x+2)=6$

Combine like terms:

$x+x+1+x+2=6\\x+x+x+1+2=6\\3x+3=6\\3x=3\\x=1$

Therefore, the least of these integers is 1.

The other two integers would be 2 and 3.

I hope this helps!
