Question

If angles of a quadrilateral are x,x+3,x+8and x+9,then find the value of x. Also ,find all the angles.
​

Answer 1

Step-by-step explanation:

Sine and cosine — a.k.a., sin(θ) and cos(θ) — are functions revealing the shape of a right triangle. Looking out from a vertex with angle θ, sin(θ) is the ratio of the opposite side to the hypotenuse , while cos(θ) is the ratio

Answer 2

Answer:

we know the sum of quadrilateral = 360degree

Step-by-step explanation:

= x + (x+3) + (x+8) + (x+9) = 360 degree

= 4x + 3 + 8 + 9 = 360 degree

= 4x + 20 = 360 degree

= 4x = (360 - 20) degree

= 4x. = 340 degree

= x. = 340 / 4

= x. 85 degree
