I do t know how to do it
Luba_88 [7]

We know: the sum of the angles measures in a triangle is 180°.

Therefore we have the equation:

64° + 75° + α = 180°

139° + α = 180°      <em> subtract 139° from both sides</em>

α = 41°

α and ∠2 are Supplementary Angles - they add up to 180°.

α + m∠2 = 180°

41° + m∠2 = 180°    <em>subtract 41° from both sides</em>

<h3>m∠2 = 139°</h3>

2x-4<br> 30<br> 15x - 30<br> PAP
Alex787 [66]

Answer:

\frac{2}{25}

Step-by-step explanation:

Given expression,

\frac{\frac{2x-4}{30} }{\frac{15x-30}{18} }

=>\frac{\frac{2(x-2)}{30} }{\frac{15(x-2)}{18} }

We see that (x-2) is common in both numerator and denominator

hence canceling out we get:-

\frac{2*18}{30*15}=\frac{2}{25}

Answer=\frac{2}{25}
