Question

in given fig if angle A and B are in 2:3 ,find measure of angle C, also , angle A + angle B = 90​

Answer 1

Answer:

Step-by-step explanation:

let ∠a=2x and ∠b=3x

∠a+∠b=180°      (Adjecent angles on straieth line are supplymentry)

→$2x+3x=$180 °

⇒5x=180°

→$x=\frac{180}{5}$= 36°

Now ∠b=3x=3×36° = 180°

∠c=∠b          (vertically opposite angles)

→∠c=108°

m∣∣n and l is transversal

∴∠h=∠c     (corresponding angle)

⇒∠h=108°

Answer 2

Let the ratio be x.

2x+3x=90

5x=90

x=18

2x=2×18=36 a=36

3x=3×18=54 b=54

therefore,

b+c+x=180

54+90+x=180

x=180-144

x=36

then

c=126
