Question 155314
Let {{{T}}} & {{{U}}} be supplement angles={{{180degrees}}}
so, {{{angle(U)=(x)deg}}}
{{{angle(T)=20+4x}}}--> to satisfy the condition:20 more 4 times the supplement
Therefore:
{{{T+U=180}}}
{{{20+4x+x=180}}}
{{{5x=180-20}}}
{{{5x=160}}} ----> {{{cross(5)x/cross(5)=cross(160)32/cross(5)}}}
{{{x=32degress}}}-------------------------> angle U
{{{20+4(32)=20+128=148degrees}}} ---------> angle T
The sum: {{{32+148=180deg}}}, supplementary angles
