Answer:
Step-by-step explanation:
<u><em>The correct question is</em></u>
Angle a and angle b are vertical angles
Angle a =8x+6
Angle b= 4x+38
Solve for x and find the measure of angle b
we know that
<u><em>Vertical Angles</em></u> are the angles opposite each other when two lines cross. They are always congruent.
m∠a=m∠b -----> by vertical angles
substitute the given values
solve for x
<em>Find the measure of angle b</em>
substitute the value of x

Step-by-step explanation:
Given : The temperature of the liquid changed by over minutes.
We can write
Now, the statement becomes ,
The temperature of the liquid changed by over minutes.
i.e. temperature changed in minutes =
Now, by Unitary method,
The temperature changed in 1 minute =
⇒ The temperature changed in 1 minute = or

Answer:
r = 14.5
Step-by-step explanation:
AD is the perpendicular bisector of chord EC, so is the diameter of the circle. The radius is half the diameter.
r = AD/2 = (AB +BD)/2 = (25 +4)/2 = 29/2
r = 14.5
