Question

2. The angles of a quadrilaterals are 4(x-1), (3x-5), (4x+21)
and 3(x+4) Find the angles?
​

Answer 1

Answer:

Step-by-step explanation:

we know that,

all angles of a quadrilateral are equal to 360 degrees

therefore,

4(x-1) + (3x-5) + (4x + 21) + 3(x+4) = 360

4x-4 + 3x-5 + 4x + 21 + 3x + 12 = 360

4x + 3x + 4x + 3x - 9 + 33 = 360

14x + 24 = 360

14x = 360 - 24

14x = 336

therefore x = 24

now, put the value of x in the given angles

like, for 4(x-1)= 4x-4= 4(24)-4= 96-4= 92 degrees
