Please give the answer ​

Answer 1

Answer:As it is given that it is a square , all the angles will be 90°..... so , ↓

43°+x°=90°x=90-43x=47°

So, now we know 2 angles of the ∆ and by applying the property of all ∆ that sum of all angles of a ∆ is 180° , we get :

x+62+y=18047+62+y=180109+y=180y=180-109y=71°So,

we now also know that ,

a°+y°=90 {all angles of square are right angles} :

a+y=90a=90-ya=90-71a=19°

Thus, the measure of angle a is 19°......Hope it helps.....Mark it a
