6. Find the supplements of the following c) x + 45°
angles:
b) 108°
d) į right angle
a) 65°

c) 135°

b) 72°

d) 90°

a) 115°

Step-by-step explanation:

A supplementary pair are two angles whose measures added is equal to 180°. Set an equation with the given values plus a number (the other angle) equal to 180:

c)

Solve. Subtract 45 from both sides:

The supplement is 135°

b)

Solve. Subtract 108 from both sides:

The supplement is 72°

d)

Solve. Subtract 90 from both sides:

The supplement is 90°

a)

Solve. Subtract 65 from both sides:

The supplement is 115°

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
