Question

If A = 450, B = 750, prove that a + c)2 = 2b.​

Answer 1

Answer:

hope you like have a nice day

Step-by-step explanation:

a/sinA = b/sinB = c/sinC = k

a= k/root2

b= root3k/2

a+ root2 b = k(1+root3)/root2 -----(eq 1)

b/sinB =k

b= sin 75 * k

k= 2root b/(root3+1)

Substitute value of k in equation 1)

a + root c = 2b

Answer 2

Answer:

525

Step-by-step explanation:

Given, A = 450

           B= 750

To proove = c

Proof = 450 + 2 (c) = 2(750)

          450 + 2 (c) = 1500

          2c = 1500 - 450

          2c = 1050

          c = 1050/2

          c = 525
