Hey there! I'm happy to help!
A proportional equation follows the form y=kx, where k is the constant of proportionality.
Answer 1 is wrong because there is something added.
2 is correct as it follows this format.
3 is incorrect as it does not follow this format.
4 is correct as it follows the format (k is 1)
5 Is correct because it follows this format.
6 is not correct because there is a 1 added, which does not follow the format.
Therefore, the correct answers are 2, 4, and 5.
Have a wonderful day! :D
I believe it's always a parallelogram??
Answer:
2√2
Step-by-step explanation:
<u>By </u><u>using </u><u>trigonometry,</u>
sin 45° = x/4
x = 4sin 45°
x = 2√2
<u>By </u><u>using </u><u>Pythagorean</u><u> </u><u>theorem</u><u>,</u>
Since you know that it is an isosceles triangle and it's also a right-angled triangle,
4² = x² + x²
16 = 2x²
x² = 8
x = √8
= 2√2
I'm pretty sure it's 27.25 because 109 ÷ 4= 27.25
