Answer:

Plz mark as brainliest

Step-by-step explanation:

1.

   let the angle be 3x, 5x and 10x

   therefore sum of angle= 18x

   as we know sum of angles of triangle is 180°

   therefore 18x = 180°

  ⇒ x=10°

therefore angles are 30°, 50° and 100°  ANS

2.

   [{($\frac{13}{4}$+$\frac{26}{5}$)+($\frac{27}{5}$-$\frac{5}{9}$)}-$\frac{3}{8}$]

[$\frac{65+104}{20}$+$\frac{243-25}{45}$-$\frac{3}{8}$]

$\frac{3042+1744+360}{360}$

$\frac{5146}{360}$

$\frac{2573}{180}$ ANS
