Answer:
Step-by-step explanation:
To solve the triangle means to find ALL unknown elements of Δ ( sides and angles )
JH² = 8² + 7² = 113
JH = √113 ≈ 10.63 m
m∠H = β
[tex]\frac{8}{7}[/tex] = tan β ; β = arctan [tex]\frac{8}{7}[/tex] = [tex]tan^{-1}[/tex] [tex]\frac{8}{7}[/tex] ≈ 48.814°
m∠H ≈ 49 °
m∠J = 90° - 49° = 41 °
