Simplified :(5x+4y)(5x−4y)

=(5x+4y)(5x+−4y)

=(5x)(5x)+(5x)(−4y)+(4y)(5x)+(4y)(−4y)

=25x2−20xy+20xy−16y2

=25x2−16y2

hope this helps!

Tan² B = 4
(tan B)² = 4
tan B = ±2

Basic Angle
= tan^-1 2
= 63.4° (1dp)

B = 63.4°, 116.6°, 243.2°, 296.6°

Assuming you're actually supposed to present your answers in 0dp, then all answers apply.
