A student council has five officers of which three girls and to our boys have two officers are chosen a random to attend a meeting with the principal what is the probability that the first office chose it is a girl and the second is a boy

Therefore

m Angle 1 = m Angle 2  = 31° ...Justified

Step-by-step explanation:

Given:

m angle 1 = ( 3x + 10 )°

m angle 2 = ( 5x - 4 )°

To Find:

m∠1 = ?

m∠2 = ?

Solution:

Vertical Angles:  

The angles opposite each other when two lines cross. They are always equal.

∴ m Angle 1 = m Angle 2

Substituting the given values we get

Substituting ' x ' in Angle 1 and Angle 2 we get

m Angle 1 = 3 × 7 + 10 = 31°

m Angle 2 = 5 × 7 - 4  = 31°

Therefore

m Angle 1 = m Angle 2  = 31° ...Justified
