Sansa was explaining the meaning and usefulness of the statement tan 40° ≈ 0. 84. Which true statements below could be part of that explanation? Select all that apply.

o All right triangles with an acute angle of 40° are similar to each other.

o The sum of the squares of the legs of right triangles with a 40° angle equal 40".

o Knowing that tan 40° ≈ 0. 84 is enough information to calculate the sides of any 40°-

50°-90° triangle.

o If you know tan 40° ≈ 0. 84 and the length of the leg opposite to the 40° angle, then

you can calculate the length of the other leg.

o The ratio of the opposite side to the hypotenuse in any right triangle with an angle of

40° is always approximately 0. 84

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

the answer is (-4,-4)

hope this ! : d

the answer is 21%.

-3 degrees
