Answer:
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
= tan β ; β = arctan = ≈ 48.814°
m∠H ≈ 49 °
m∠J = 90° - 49° = 41 °
10.63
To find the Hypotenuse we need to use Pythagorean Thereom. So plugging in the formula the square root of A squared plus B squared you get 10.63
