Question

ABCD is a rhombus. What is the value of x?

B
(3x+10)°
A
8
20
10
12
D
C
(2x+20)°

Answer 1

Explanation:

The opposite angle of rhombus are equal

so,

here,

or,3x+10=2x+20

or,3x-2x=20-10

Therefore x=10

Answer 2

3x+10+2x+20=180(oppite <s of parallogram)

30+3x=180

3x=180-30

3x=150

x=50
