Question

in the following triangle, find the value of x and y
A=50°, a=y, B=x°, b=8cm, C=?, c=y
use sin rule

Answer 1

Answer:

x = 80 and y = 6.22

Step-by-step explanation:

Sin Rule formula = Sin(A)/a = Sin(B)/b = sin(C)/c (for finding angles)

and

a/Sin(A) = b/Sin(B) = c/Sin(c) (for finding sides)

given

A=50°, a=y

B=x°, b=8cm

C=?, c=y

for Finding Angles

Sin(A)/a = Sin(C)/c

Sin50°/y = Sin?/y

? = 50° or C = 50°

As the sum of angles in a triangle is 180°

therefore A=50°, C=50° then B=80°

therefore B=x°=80°

for finding sides

a/Sin(A) = b/Sin(B)

y/sin50° = 8/sin80°

Sin80°/Sin50° = 8/y

y = (8×Sin50°)/sin80°

therefore y= 6.22
