a=30

b=34

c=70

Step-by-step explanation:

a=35°b=55°c=110°

Step-by-step explanation:

a=35°[by vertical opposite angles]

a+b+90°=180°

35°+b+90°=180°

125°+b=180°

b=180°-125°

b=55°

70°+c=180(°by linear pair)

c=180°-70°

c=110°

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
