The answer is the third option.
x and y are both to the first degree so we know it makes a straight line.
Next check the ordered pairs to see which set are true in the equation.

What is the measure of minor arc BD?

Vaselesa [24]

Answer:

$minor\ arc\ BD=100^o$

Step-by-step explanation:

The picture of the question in the attached figure

we know that

A circumscribed angle is the angle made by two intersecting tangent lines to a circle

In this problem

BC and CD are tangents to the circle

BC=CD ----> by the Two Tangent Theorem

That means

Triangle ABC and Triangle ADC are congruent

$m\angle BAC=m\angle DAC$

Find the measure of angle BAC

In the right triangle ABC

$m\angle BAC+m\angle BCA=90^o$

substitute given value

$m\angle BAC+40^o=90^o$

$m\angle BAC=90^o-40^o=50^o$

Find the measure of angle BAD

$m\angle BAD=2m\angle BAC$

$m\angle BAD=2(50^o)=100^o$

Find the measure of minor arc BD

we know that

$minor\ arc\ BD=m\angle BAD$ -----> by central angle

therefore

$minor\ arc\ BD=100^o$

Lenny bought a motorcycle . He paid 12.5% in tax . The tax added $1437.50 to the price of the motorcycle . What was the price of

vredina [299]

Answer:

$11500

Step-by-step explanation:

Given

Tax amount=$1437.50

Tax percentaege=12.5%

So, we have to find the price of motorcycle whose 12.5% is 1437.50

Mathematically writing,

Let

x be the price of motorcycle without tax

then, the equation will be written as:

x*0.125=1437.50

x= 1437.50/0.125

x=11500

So the price of motorcycle without tax was $11500..

Solve each equation by taking square roots 9v^2=25

lisov135 [29]

9v^2=25
v^2 = 25/9
v^2 = (5/3)^2
v = + 5/3 and v = -5/3
