Answer 1

the angles of the triangles are 42°, 105°, 33°.

refer the attachment.

Answer 2

Step-by-step explanation:

✴️ Given :

one exterior angles = 105°

two interior opposite angles are in ratio of = 2:5

hence, interior opposite angels = 2x and 5x

another interior angle = y

✴️ To find :

Angles of triangle .

✴️ Solution :

exterior angles = sum of opposite angles......( property of triangle)

so,

105° = 2x+5x

105° = 7x

x = 105/7

x = 15°

substituting the value of x in 2x and 5x

two opposite angles = 2×15=30°

nd = 5×15= 75

{According to property of triangle : sum of angles of triangle is 180° }

so,

30° + 75° + y = 180°

105° +y = 180°

y = 180° -105°

y = 75°

so, the angles of triangle are as =====>

30°, 75°, 75°
