Sin theta=-1/2 then cos theta=​

Mathematics
1 answer:
zepelin [54]3 years ago
4 0

Answer:

<h2>cos 30°= 0.866</h2>

Step-by-step explanation:

Step one:

Applying the SOH CAH TOA principle

assuming all dimensions are in cm

Step two:

Given data

opposite= 1 cm

hypotenuse= 2 cm

<h3>we can now solve for θ</h3>

Sin(θ)= opp/hyp

Sin(θ)= 1/2

Sin(θ)= 0.5

θ= sin-1 0.5

θ= 30°

hence  from tables cos 30°= 0.866

never [62]

Answer:

0

Step-by-step explanation:

We can find the slope using the slope formula

m = ( y2-y1)/(x2-x1)

    = ( 7-7)/(5-8)

    = 0/-3

   = 0

Andreas93 [3]

Step-by-step explanation:

given Tony can type at a constant rate of 110 words every 2 minutes.This means tony can type 55 words in every minute.

A- Tony can type W words in T minutes. W*T=M (M=Minutes Tony typed)

B-  Tony can type 1100 words in 20 minutes. as 55*20=1100.

C- Yes, Tony can type the essay. Why: because in this equation w=55 and t=30 minutes so t*w=30*55=1650 so yes, Tony can write the essay.

Write the equation of a line in the given form.
Gnom [1K]

Answer:

y = \frac{1}{4}x - 5

Step-by-step explanation:

Slope intercept form: y = mx + b

Find slope:

m = (y₂ - y₁) / (x₂ - x₁)

   = (-5 - (-4)) / (0 - 4)

   = -1 / -4

   = 1/4

Find y intercept using anyone of the given points and slope from above:

y = mx + b

-5 = \frac{1}{4}(0) + b

b = -5

Now use the above slope and y intercept to create equation of a line:

y = \frac{1}{4}x - 5
