Question

Due today!

Given A = 50° B = 79° and C = 8

Solve the triangle for the value of a. Round your answer to two decimal places.

Answer 1

Answer:

first, solve for the angle c

let angle c be x

50+79+x=180

angle in a triangle

129+x=180

collect like terms

x=180-129

x=51

using sine rule

a/sinA=c/sinC

a/sin50=8/sin51

cross multiply

a×sin51=8×sin50

therefore a= 8×sin50/sin51

note; to get the real answer solve the numerator first before dividing

am sorry I could have solved it completely for u but my calculator is not good

Answer 2

Answer:

A=50

B=79

C=51

a=7.88572

b=10.10495

c=8

Step-by-step explanation:

b/sin(B) = a/sin(A) = c/sin(C)

b/sin(79) = 8/sin(51)

b = 10.10495

a/sin(50) = 8/sin(51)

a=7.88572
