pls answer my question

Answer 1

Answer:

option a) and b) are the correct answers

as Sum of all angles of a quadrilateral=360°

2x+5x+4x+1x=360

12x=360

x=360/12=30

2x=2×30=60

5x=5×30=150

4x=4×30=120

1x=1×30=30

hope it helps

Answer 2

Answer:

Sum of all angles of quadrilateral is 360°

$then \: 2x + 5x + 4x + 1x = 360$

$12x = 360$

$x = \frac{360}{12}$

$x = 30$

$2 \times 30 = 60 \\ 5 \times 30 = 150 \\ 4 \times 30 = 120 \\ 1 \times 30 = 30$

$answer \: is \: a \: and \: b$
