What is a triangle?

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

Triangle XYZ.

∠Y = 90°

Now,

The sum of the three angles must be 180°.

So,

∠X + ∠Y + ∠Z = 180

∠X + ∠Z = 180 - 90

∠X + ∠Z = 90

Thus,

∠X + ∠Z = 90

-1/2 = m -7/4
solve for m

Answers

Answer:

[tex]\boxed {m = \frac{5}{4}}[/tex]

Step-by-step explanation:

Solve for the value of [tex]m[/tex]:

[tex]-\frac{1}{2} = m - \frac{7}{4}[/tex]

-Switch sides:

[tex]m - \frac{7}{4} = -\frac{1}{2}[/tex]

-Add both sides by [tex]\frac{7}{4}[/tex] and the least common multiple of both [tex]2[/tex] and [tex]4[/tex] is [tex]4[/tex]. So, convert [tex]-\frac{1}{2}[/tex] to a fraction with denominator [tex]4[/tex]:

[tex]m - \frac{7}{4} + \frac{7}{4} = -\frac{1}{2} + \frac{7}{4}[/tex]

[tex]m = -\frac{2}{4} + \frac{7}{4}[/tex]

-Since both [tex]-\frac{2}{4}[/tex] and [tex]\frac{7}{4}[/tex] have the same denominator, then you would add the numerators:

[tex]m = \frac{-2 + 7}{4}[/tex]

[tex]\boxed {m = \frac{5}{4}}[/tex]

Therefore, the value of [tex]m[/tex] is [tex]\frac{5}{4}[/tex].
