Sagot :
Answer:
14 ° ; 83 °
Step-by-step explanation:
( 14x - 1 )° + ( 2x + 2 )° = 97°
14x - 1 + 2x + 2 = 97
16x = 96
x = 6
m∠BCA = ( 2 × 6 + 2 )° = 14 °
m∠ABC = ( 14x - 1 )° = 83 °
Sum of two interiors is equal to the exterior

[tex]\\ \sf\Rrightarrow 16x+1=97[/tex]
[tex]\\ \sf\Rrightarrow 16x=96[/tex]
[tex]\\ \sf\Rrightarrow x=6[/tex]
- m<BCA=2(6)+2=14°
- m<ABC=14(2)-1=27°
