Question

PLEASE HELP I GIVE THANKS

Answer 1

Angle 5 is 72 degrees. due to supplementary angles

Answer 2

The sum of 4 and 5 has to be equal to : 180 degrees. Because they make a straight angle (which its measure is 180). So we know '4' 108:

`{ 108 }^( o )+\quad '5'\quad =\quad { 180 }^( o )\\ '5'\quad =\quad { 180 }^( o )\quad -\quad { 108 }^( o )\\ '5'\quad =\quad { 72 }^( o )`

5 is equal to
`{ 72 }^( o )`
