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.

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

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

step-by-step explanation:

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
