Answer:

The answer is A. 2.0

Step-by-step explanation:

One of the angles is a right angle, because x is the tangent of that circle. The other radius is 1.5, since all radius are equal to each other. Then you use the Pythagorean theorem (a²+b²=c²). C is always the hypotenuse. The hypotenuse in this triangle is the 1.5 + 1 line. A and b can be changed within each other. I put A = 1.5, B = x, and C = 2.5. My equation was 1.5²+x²=2.5². Remember the formula can also be x²+1.5²=2.5² as well. Then you solve the equation you just made. You multiply everything by each other, because of the ² (I forgot the name of it, hehehe). You will get 2.25+x²=6.25. Then you subtract 2.25 to both side. x²= 4. Then you square root both sides to make x by itself. x=2. That's how you get 2 as your answer

Answer: B

Step-by-step explanation:

The equation $y+2=\frac{3}{4} x-8$ is not yet in slope-intercept form( $y=mx+b$ ). Simply subtract 2 from both sides to turn the equation into slope intercept form as $y=\frac{3}{4}x-10$ . For a line to be perpendicular to another, it must have an opposite reciprocal slope. A reciprocal is the fraction reversed, where the numerator is the denominator and vice versa. Thus, 3/4 would become 4/3. The opposite reciprocal of 3/4 would be -4/3.

The slope of the line given is 3/4. Thus, simply plug in the opposite reciprocal of 3/4 for the slope to get: $y=-\frac{4}{3} x+b$ . Then, because the line passes through -12, 1, plug those values in for x and y, respectively.
