BC is 28 units long.

To find x, write the equation 4x - 7 = 2x + 7, as sides AC and AB are equal because the triangle is isosceles. The triangle is isosceles due to the base angles theorem. Once we get x, which is 7, we need to substitute it into the equation of BC. We then get 4(7), which equals 28 units.

Which of the following functions is graphed below?

pishuonlain [190]

Answer: B

The piece wise functions first part says: x is less than it equal to one and has a vertical shift down 4. which would mean the circle is closed and shaded down.

The second part of the function says x is greater than one and has a vertical shift up 3. This would mean it is an open circle and is shaded up.

If x= 35. what is the value of Y?<br> 0 35

Grace [21]

Answer:

Step-by-step explanation:

In a triangle all the angles = 180 degrees

That means: x + y + 90 = 180

x + y = 180 - 90 = 90

35 + y = 90

y = 90 - 35

y = 55 degrees
