Step-by-step explanation:
[tex]4b + b + {75}^{0 } = {180}^{0 } \\ 5b + {75}^{0} = {180}^{0} \\ 5b = {180}^{0} - {75}^{0} \\ 5b = {105}^{0} \\ b = {105}^{0} \div 5 \\ b = {21}^{0} \\ 4b = 4 \times {21}^{0} = {84}^{0} \\ [/tex]
[tex]4b = a \\ a = {84}^{0} [/tex]
[tex]2c + a = {180}^{0} \\ 2c + {84}^{0} = {180}^{0} \\ 2c = {180}^{0} - {84}^{0} \\ 2c = {96}^{0} \\ c = {96}^{0} \div 2 \\ c = {48}^{0} [/tex]
