If the angles of a quadrilateral are in the ratio 3:6:8:13 then the largest angle is?

$\huge\star{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}\star$

156°

Given ratio of angles of quadrilateral ABCD is 3:6:8:13

Let the angles of quadrilateral ABCD be 3x,6x,8x,13x respectively.

⇒3x+6x+8x+13x=360° [ Sum of all angles of a quadrilateral is 360° ]

∴x=12°

∴∠A=3×12 °

=36° ∠C=8×12 °

=96°

⇒∠B=6×12°

=72° ∠D=13×12°

=156°

∴ The largest angle =156°

Hence, the answer is 156°.

Answer 2

QUESTION:- If the angles of a

quadrilateral are in the ratio

3:6:8:13 then the largest angle is

ANSWER:- 3:6:8:13

$3x + 6x + 8x + 13x = 360 \\ \\ 30x = 360 \\ \\ x = \frac{360}{30} \\ \\ x = 12 \\ \\ 3x = 3 \times 12 = 36 \\ \\ 6x = 6 \times 12 = 72 \\ \\ 8x = 8 \times 12 = 96 \\ \\ 13x = 13 \times 12 = 156 \\ \\ largest \: \: angle \: \: is \: 156 \: (13)$
