Step-by-step explanation:
L.H.S =
sin15°+tan65°
sin(90°-75°)+tan(90°-25°)
cos75°+cot25°
or; cot25°+ cos75°. R.H.S
Its a bar graph, hope that helped!
Answer:
Q is the centroid the after you can do it your self by looking forward
Answer:
l = 40
Step-by-step explanation:
Since Perimeter comes from P = 2l + 2w so 180 = 2l + 2(50)
180 = 2l + 100
180-100 = 2l
80 = 2l
so l = 40
