Find the angle marked with the ? mark
Yuri [45]

Answer:

53 degrees

Step-by-step explanation:

Angle N = angle E

because angle made by joining end points of same chord on circumference are always equal.

so angle E = 37

Angle D = 90 ( because angle made by diameter on circumference is 90 degrees)

Now in Triangle DEC. Sum if all the angles of triangle us 180

Angle D + angle E + ? = 180

37 + 90 + ? = 180

127 + ? = 180

? = 180 - 127

? = 53 degrees

Change the equation 2x - 5y + 4 = 0 into an equivalent equation written in the slope-intercept form
mamaluj [8]

Answer: The equation in slope intercept form is

y = 2x/5 + 4/5

Step-by-step explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = y intercept

m represents the slope of the line.

The given equation is expressed as

2x - 5y + 4 = 0

Adding 5y to the left hand side and the right hand side of the equation, it becomes,

2x - 5y + 5y + 4 = 5y

5y = 2x + 4

Dividing the left hand side and the right hand side of the equation by 5, it becomes,

5y/5 = 2x/5 + 4/5

y = 2x/5 + 4/5

If the sum of the measures of the interior angles of a convex polygon is 2160°, how many sides does the polygon have?
olya-2409 [2.1K]
Remember your formula is 180(n-2) where n=number of sides. So start out by dividing by 180, then add 2 to get the sides.
