Find the value of each variable.

Question

1. These questions, I'm just bad at solving in general...please explain step by step

A. a=59°; b=49°; c= 72°; d=98° B. a=59°; b= 52°; c=72°; d= 96° C. a=118°; b=49°; c=144°; d= 98°

2.Assume that lines that appear tangent are tangent. Find the value of the variables.

A. a=40; b=130; c=70 B. a=36; b=140; c=70 C. a=20; b=160; c=90 D. a=40; b=140; c=90

Answer 1

#1

Label it correctly.

α=ab*sinγ/2

β=bc*sinα/2

γ=ac*sinβ/2

α smallest angle

β mid

γ hypotenuse

a side opposite α

b β

c γ

a/sinα=b/sinβ=c/sinγ
