Question

Q :- In a triangle ABC , <B = 900 , <A = 300 , BC = 6cm , Find <B and AC.​

Answer 1

Step-by-step explanation:

hello friend

as we know sum of angles in a triangle is 180

given angle b = 90

angle a = 30

so sum will be 90 + 30 = 120

remaining angle will be 60 I.e 180-120

so it might be angle c which will be equal to 60 degrees

now as angle b is 90 it is a right angled triangle at b

given bc = 6 cm

the triangle will be as shown in figure

now by Pythagoras theorem the triplets are 6,8,10

as ac is hypotenuse it will be longest length I.e 10 cm

and remaining side ab will be 8 cm.

please check the angles in question you have asked you have sent b two times check it correctly and check my solution

hope it helps you my friend
