Question

please help me its is very important hence please help me if u know then answer me​

Answer 1

Answer:

30° + x + x = 180°

Step-by-step explanation:

30° + 2x = 180°

180 - 30 = 150°

150° = 2x

x = 150 ÷ 2

x = 75°

y + y + y = 180

3y = 180°

y = 180 ÷ 3

y = 60°

Answer 2

Given data,

∠CAB=30°

To calculate,

x=y=?

Calculations,

as we know that,

• diagonals of a rhombus bisects the opposite angles
• sum of adjacent angles of rhombus is 180°

.'.∠DAB=60°

∠DAB+∠ABC=180°

60°+∠ABC=180°

∠ABC=120°

as diagonal DB bisecting angle ∠ABC

$x = \frac{120}{2} \\ x = 60$

Now in ∆ADB

∠DAB+∠DBA+∠ADB=180°

60°+60°+y=180°

y=60°

Final answer,

x=y=60°
