Question

please teel me the answer​

Answer 1

Step-by-step explanation:

Angle A +angle B + angle C =180°...(sum of all angles of triangle =180°

45°+60°+angle C =180°

Angle C = 180 - 105

Angle C =75°

Angle ACB = Angle ECD.... (vertically opposite angles)

Therefore, angle ECD=75°

Angle D + angle C +angle E=180°..... (Sum of all angles of triangle is 180 °)

X°+75+35=180°

X°=180-110°

X=70°

Answer 2

x=70

Step-by-step explanation:

1 triangle= 180°

• 1st triangle=180-( angle 45°+angle 60°)

• =180-105
• other angle=75°
• 1st triangles angle 75° opposite angle is 2nd triangles blank angle is 75°.
• x=180-(75+35)
• x=180-110
• x=70° ( Answer)
