Question

Can someone help me with this please!~

The measures of the angles of △ABC are given by the expressions in the table.

Answer 1

a=120

c=45

i took the quizzzz

Answer 2

Note that sum of triangle interior angles is 180. So,


`(12x+12)+15+(3x+18)=180`


`15x+45=180`


`15x=135`


`x=9`

Since
`A=12x+12=12.9+12=120`

And
`C=3x+18=3.9+18=45`
