You can count from 6-10 and you would get c) 5/10
I think is 70 because you first sum 18 + 6, then your answer is 24 and you subtract 90 - 24 because the triangle is a right angle that is 90 degrees. That got me 66 and I round it to the nearest tenth and I get 70.
ABCD is a parallelogram ⇒ BE = DE
So: 7x - 12 = 3x + 4
⇔ 7x - 3x = 4 + 12
⇔ 4x = 16
⇔ x = 16/4 = 4
⇒ BE = 7(4) - 12 = 28 - 12 = 16
⇒ DE = 3(4) + 4 = 12 + 4 = 16
⇒ BD = BE + DE = 16 + 16 = 32
Answer: BD = 32
Ok done. Thank to me :>
