Please help I’ll mark you as branlst
wariber [46]

Answer:

6

Step-by-step explanation:

Since the degree of the angle is 45, we know that the triangle is isosceles. That means that the sides of the triangle, not including the hypotenuse, has a length of 3√2.

Using the Pythagorean theorem, which is a^2 + b^2 = c^2, we have (3√2)^2 + (3√2)^2 = c^2.

Note: c is the hypotenuse of the triangle.

18 + 18 = c^2

= 36 = c^2

Therefore, c = 6.

Name the property used to make the conclusion. If x=3, then 5x=15.
bulgar [2K]
Note that both sides were multiplied by 5.

So that would be "Multiplication Property of Equality."

Basically, this property states that if a=b, then ac = bc.

NemiM [27]

Answer:

15 months

Step-by-step explanation:

35x+20=545

Subtract 20 from both side to figure out how many months he paid for....

35x+20-20=545-20

35x=525

Divide 35 on both sides....

x=15

Therefore, he has been a member for 15 months

Check:

35(15)+20=545

525+20=545

545=545

IT'S CORRECT!!!
