Find the sum 5 3/4 and 3 and 1/6 and show them how me how you got to work

5 3/4 + 3 1/6

Make the 3/4 and 1/6 have common denominators. The least common denominator is 12. Multiply 3/4 by 3 on both sides and 1/6 by 2 on both sides.

5 3/4 ⇒ 5 9/12
3 1/6 ⇒ 3 2/12

Now you can add them up.

5 9/12 + 3 2/12 = 8 11/12

The answer is 8 11/12.

Step-by-step explanation:

given :

y = 120 degree

z = 57 degree

angle x = ?

first lets find angle c in triangle BDC

angle c + z = y (sum of two interior opposite angle is equal to the exterior angle formed)

angle C + 57 = 120

angle C = 120 -57

angle C = 63 degree

Now lets find angle B in triangle BDC

angle B + angle C + z = 180 degree (sum of interior angles of a triangle)

angle B + 63 + 57 = 180

angle B + 120 = 180

angle B = 180 - 120

angle B = 60 degree

now for angle x

angle B + z = angle x (sum of two interior opposite angles is equal to the exterior angle formed)

60 + 57 = x

117 = x
