Answer:
3.50 divided by 5=70 70 times five is 3.50
Step-by-step explanation:
The slope of a line perpendicular to another line is the opposite reciprocal of the slope of that line. Basically, the slopes of two perpendicular lines multiply to -1. The slope of this line is -1/5. To find the slope of a line perpendicular, we need to find out what number, multiplied by -1/5, would make -1. Or, we can take the opposite reciprocal (it's the same answer). This number is 5, so the slope of a line perpendicular to this line is 5.
Answer: 60 degrees
Step-by-step explanation:
1. Make a right triangle where the right angle is and label the hypotenuse r.
2. Since the chord is equal to r and a 90-degree angle is formed at the intersection, the chord is bisected. Therefore, the chord segment is 1/2 r.
3. Since we have to solve for the intercepted arc, we must find the central angle ( the angle of the right triangle closest to the dot/center) of the arc, which in this case is the sin, or 0.5r/r.
4. We must get rid of the fraction in the numerator, so multiply both the numerator and denominator by 2 which gets you 1r/2r.
5. The r's cancel out, leaving you with 1/2.
6. Since we have to find the angle measure, you must take the negative sin of 1/2 which is 30 degrees.
7. Finally multiply by 2 since you only solved one bisected portion to get 60 degrees.
