Anyone help me please

Solution,

As we have,

⇒2SinACosB=Sin(A+B)+Sin(A-B)

Now,

$2sin7\alpha .cos2\alpha =sin9\alpha +sin5\alpha \\\\LHS=2sin7\alpha .cos2\alpha \\\\LHS=sin(7\alpha +2\alpha )+sin (7\alpha -2\alpha )\\\\LHS=sin9\alpha +sin5\alpha$

Hence, LHS=RHS

Line a is parallel to line b, m∠1=2x+44 and m∠ 5=5x+38 Find the value of x.

Mumz [18]

Line a is parallel to line b:
m∠1=m∠ 5, because they are correspondent angles, then:
2x+44=5x+38
Solving for x:
2x+44-2x-38=5x+38-2x-38
6=3x
3x=6
Dividing both sides of the equation by 3
3x/3=6/3
x=2
