cos(A)= 1/(sqrt(65)),cos(B)= 1/(sqrt(5))

cos (A) = \frac{1}{65}, cos (B) = \frac{1}{5}

No Solution for A \in R

Solution steps

cos (A) = \frac{1}{65}, cos (B) = \frac{1}{5}

Simplify

\frac{1}{65} : \frac{65}{65}

Apply trig inverse properties

A = arccos (\frac{65}{65}) + 2 πn, A = 2 π - arccos (\frac{65}{65}) + 2 πn

Solutions for the range

cos (B) = \frac{1}{5}

No Solution for A \in R

sin (θ) = 0.9063

a \cdot sin (x) + b \cdot cos (x) = 0

cos (θ) = - 0.19

9 cos^{2} (x) = 2

tan (θ) = \frac{6}{14}
