Verify a ÷ b ≠ b ÷ a , if a = −3/4 and b = 4/5
Shalnov [3]

Given:

a=-\dfrac{3}{4}

b=\dfrac{4}{5}

To verify:

a\div b\neq b\div a

Solution:

We have,

a=-\dfrac{3}{4}

b=\dfrac{4}{5}

Now,

a\div b=\dfrac{a}{b}

a\div b=\dfrac{-\dfrac{3}{4}}{\dfrac{4}{5}}

a\div b=-\dfrac{3}{4}\times \dfrac{5}{4}

a\div b=-\dfrac{15}{16}               ...(i)

And,

b\div a=\dfrac{b}{a}

b\div a=\dfrac{\dfrac{4}{5}}{-\dfrac{3}{4}}

b\div a=\dfrac{4}{5}\times (-\dfrac{4}{3})

b\div a=-\dfrac{16}{15}               ...(ii)

From (i) and (ii), it is clear that

a\div b\neq b\div a

Hence verified.

Please tell me if I'm correct. If not, please tell me how you got your answer. See attatchment ASAP.
mestny [16]
You're incorrect. an angle of 155 degrees is an obtuse angle. the angle is obviously an acute angle, as it is under 90 degrees. the answer is 50 degrees, or A.

Side opposite to ∠N = ML.

<h3>What is a Right Triangle?</h3>

A right triangle has  right angle (angle 90) that is opposite to the longest side (hypotenuse).

From the image given, the right triangle has a right angle at angle M, which is oppposite to the hypotenuse, LN.

Therefore, the true statements about the triangle are:

  • Hypotenuse = LN
  • Opposite side to ∠L = NM
  • Side opposite to ∠N = ML.
