Answer 2

Answer:

b)100°

60°

20°

d)37.5%

Step-by-step explanation:

b)

let the sum of angles in triangle be 180°.

then,

the first angle be = (5/5+3+1)×180°

=(5)/9×180= 5×20= 100°

the second angle be = (3/5+3+1)×180°

= (3)/9×180°= 3×20=60°

the third angle be = (1/3+5+1)×180°

= (1)/9×180° = 1×20=20°

d)(3/8)×100

=(3/2)×25

=75/2

=37.5%
