Question

Q.2 The angles A, B, C and D in
quadrilateral ABCD are in ratio 1:2:3: 4 respectively then measure of angle of B is
a) 108°
b) 72
c) 36°
d) 144°​

Answer 1

Answer:

b is your answer

Step-by-step explanation:

1+2+3+4 = 10

360÷10=36

B= 2×36

B=72

hope it helped you

Answer 2

$\mathbb{ANSWER}$

Given ,

Ratio of angle A , B , C , D are = 1:2:3:4

Let the measures of the angles be = $x$

$\therefore$ A/Q

$\implies$ 1x + 2x + 3x + 4x = 360⁰ $(Angle\:sum\:property\:of\:a\: quadrilateral)$

$\implies$ 10x = 360⁰

$\implies$ x = $\frac{360}{10}$

$\implies$ x = 36⁰

$\therefore \angle$ B = 2 × 36⁰ = 72⁰
