Answer:

The correct option is 3.

Step-by-step explanation:

Given information: Lines r and s are parallel to each other.

If two lines intersect each other at a point then the opposite angles are called vertically opposite angles and these vertically opposite angles are always same.

From the given figure it is clear that the angle having measure d° and angle having measure 125° are vertically opposite angles. So,

d^{\circ}=125^{\circ}               (Vertically opposite angles)

d=125^{\circ}

The value of d is 125, therefore the correct option is 3.

Give the equation of the circle centered at the origin and passing through the point(0,10)
beks73 [17]

Answer:

x^{2} + y^{2} = 100

Step-by-step explanation:

The equation of a circle has the following format:

(x - x_{0})^{2} + (y - y_{0})^{2} = r^{2}

In which r is the radius(half the diameter) and the centre is the point (x_{0}, y_{0})

Centered at the origin

This means that x_{0} = 0, y_{0} = 0

Passing through the point(0,10)

The radius is the distance of any point in which the circle passes to the centre.

Using the formula for the distance between two points.

r = D = \sqrt{(0 - 0)^{2} + (10 - 0)^{2}} = 10

So

x^{2} + y^{2} = 10^{2}

x^{2} + y^{2} = 100

Two angles are supplementary. One angle is 16° less than three times the other. Find the measures of the angles
Ivan

Answer:

Step-by-step explanation:

x and y are supplementary angles, so their sum is 180°.

x+y = 180°

x is 16° less than three times y

x = 3y - 16°

(3y-16°) + y = 180°

4y = 196°

y = 49°

x = 3y-16° = 131°
