Find the missing length QG. Round answer to nearest tenth.

The answer to your question is QG = 55.8 ft

Step-by-step explanation:

Data

QG = x

Process

1.- Find T

The sum of the internal angles in a triangle equals 180°

          G  +  Q  +  T  = 180

-Solve for T

            T  =  180 - G  -  Q

- Substitution

            T = 180 - 41 - 67

-Simplification

             T = 72°

2.- Use the law of sines to find QG

              QG / sin T = GT / sin Q

-Solve for QG

              QG = GT sinT / sin Q

-Substitution

              QG = 54 sin 72 / sin 67

- Simplification

              QG = 54 (0.951)/0.921

-Result

             QG = 55.8 ft        

Step-by-step explanation:

Considering the given triangle QGT, to determine QG, we would apply the sine rule. It is expressed as

a/SinA = b/SinB = c/SinC

Where a, b and c are the length of each side of the triangle and angle A, Angle B and angle C are the corresponding angles of the triangle. Likening it to the given triangle, the expression becomes

QG/SinT = GT/SinQ = QT/SinG

The sum of the angles in a triangle is 180°. It means that

T = 180 - (41 + 67) = 72°

Therefore

QG/Sin72 = 54/Sin 67

Cross multiplying, it becomes

QGSin67 = 54Sin72

0.921QG = 54 × 0.951

0.921QG = 51.354

QG = 51.354/0.921

QG = 55.8 ft
