Question

Evaluate sin25 degree Cos65 degree +cos25 degree sin 65

Answer 1

Answer:

Step-by-step explanation:

Sin25°cos65°+cos25°sin65°

Sin(90-65°)cos65°+cos(90-65°)

Cos^265°+sin^26°=1

Answer 2

q-sin25°cos65°+cos25°sin65°

sinA=cos(90-A)°

cosB=sin(90-A)°

sin25°sin25°+cos25°cos25°

sin(square)A +cos(square)A=1

sin(square)25+cos(square)25=1
