Question

by how much angle A bigger than angle B in the given fig​

Answer 1

Answer:

26°

Step-by-step explanation:

$\implies$ $290°+48°+x=360°$

$\implies$ $x=360°-338$

$\implies$ $x=22°$

By angle sum property

$\implies$ $b+90°+48°=180°$

$\implies$ $b=180°-138°$

$\implies$ $\boxed{b=42°}$

$\implies$ $a+90°+22°=180°$

$\implies$ $a=180°-112°$

$\implies$ $\boxed{a=68°}$

$\implies$ $A-B=68°-42°$

$=\large\boxed{26°}$

Answer 2

Answer:

290+48+x=360degree

x=360-338x=22 degree

angle b+90+48=180 degree

b=180-138

b=42 degree

aa+90+22=180 degree

a=180-112

a=68 degree

A-b=68-42

26degree ans.
