i hope this is right, if not then I’m sorry
Step-by-step explanation:
Answer:
sin5A+sin3A=cos2A-cos6A
2SIN((5A+3A)/2)COS ((5A-3A)/2)=2SIN((2A+6A)/2)SIN((2A-6A)/2)


-1/2sinA=1
-1/2=sinA
sinA=sin(180+30),sin(330)
:.A=210,330
Answer:
B
Step-by-step explanation:
AS is an angle bisector, thus the ratio of the sides of the triangle is equal to the ratio of the corresponding parts of RT, that is
=
, substituting values
=
( cross- multiply )
7.5x = 31.5 ( divide both sides by 7.5 )
x = 4.2
Thus
RT = 3.5 + x = 3.5 + 4.2 = 7.7 → B
