Question

If the two opposite angles of parallelogram is (63-3x) and (4x-7). Find the angles

Answer 1

Answer:33° and 33°

Step-by-step explanation:

The opposite angles of a parallelogram are equal so,

(63-3x)=(4x-7)

63+7=4x+3x

70=7x

x=10

(63-3x)=63-3(10)

=63-30

=33°

Also, 4x-7=4(10)-7

=40-7

=33°

Answer 2

Opposite angles of a parallelogram are congruent, so:

• -3x + 63 = 4x - 7
• -7x = -70
• x = 10

So we substitute 7 for x:

• -3x + 63
• -30 + 63
• 33

It also works the other way:

• 4x - 7
• 40 - 7
• 33

Both angles are 33 degrees. (mark brainliest)
