Answer 1

Answer is given in the attachment above.

Answer 2

$\fbox \orange {Answer:-}$

We know that that sum of the angles of a straight line = 180°

Sum of ratio = 5 + 6 + 7 = 18

First angle =

$\frac{5}{18} \times 180 \: = \: 5 \: × \: 10 \: = \: 50°$

Second angle =

$\frac{6}{18} \times180 \: = \: 6 \: × \: 10 \: = \: 60°$

Third angle =

$\frac{7}{18} \times 180 \: = \: 7 \: × \: 10 \: = \: 70°$
