Question

from the following figure find angle ACD​

Answer 1

Answer:

42°

Step-by-step explanation:

In Δ ABC

3x + 4x + x = 180°

8x = 180

x = 45/2

Substituting x in 4x

= 4 * (45/2) ⇒ 90°

In triangle ADC

Angle ACD = 180°-(48°+90°) = 42°

Answer 2

4x +3x +x = 180

8x=180

2x =45

x=45/2

angle ADC =(4×45/2)= 90

angle ACD = (90-48)=42°
