Answer:

Angle MON = 130°

Step-by-step explanation:

since, we know ;

m LON = m LOM + m MON

( m LON = 180°, because it forms a straight line, that is " linear pair " )

so,

  • =》m LOM + m MON = m LON
  • =》4x + 30° + 8x + 90° = 180°
  • =》12x + 120° = 180°
  • =》12x = 180° - 120°
  • =》12x = 60°
  • =》x = 60° ÷ 12
  • =》x = 5°

<em>x</em><em> </em><em>=</em><em> </em><em>5</em><em>°</em>

now,

=》m MON = 8x + 90°

=》m MON = ( 8 × 5° ) + 90°

=》m MON = 40° + 90°

=》m MON = 130°

Find the value of 8/15×2/13 Although these numbers aren't quite as nice as the ones from the example, the procedure is the same,
xz_007 [3.2K]

Answer:

\frac{16}{195}

Step-by-step explanation:

To obtain the result of a fractions multiplication we need to multiply both numerators and the divide by the multiplication of the denomitators. In general, given a,b,c,d real numbers with b and d not zero, we have that

\frac{a}{b}*\frac{c}{d}=\frac{a*c}{b*d}

Substituting a,b,c and d for 8,15,2 and 13 we obtain that

\frac{8}{15}* \frac{2}{13} =\frac{16}{195}
