Answer:
Step-by-step explanation:
This is because the centre is at (3,2) and the radius of the circle is 4 and you square all the terms to find the equation of the circle.
Answer:
58°
Step-by-step explanation:
<u>Start with the equation</u> 2x + 2 + 90 = 148
<em>( I got the 90 from Angle B since it is a right angle.)</em>
<u>Combine like terms</u> 2x + 92 = 148
<em>( 90 and 2 didn't have variables so you could add them together.)</em>
<u>Subtract 92 from both sides</u> 2x + 92 = 148
-92 -92
<em>(The opposite of addition is subtraction.)</em>
<u>Now write out the new equation</u> 2x = 56
<u>Divide both sides by 2</u> =
<u>You'll end up with...</u> x = 28
<u>To find the measure of angle BAC, plug in 28 where the x value is</u> 2(28) + 2
<u>This gives you the answer</u> 58°
