Answer: Angle L = 54 degrees
Step-by-step explanation:
The sum of the angles in a triangle is 180 degrees. This means that
Angle J + Angle K + Angle L = 180 degrees
Looking at the triangle,
Angle J = 5x degrees
Angle K = 2x degrees
Angle L = 3x degrees
Therefore,
5x + 2x + 3x = 180
10x = 180
Dividing the left hand side of the equation and the right hand side of the equation by 10, it becomes
10x/10 = 180/10
x = 18
Therefore,
Angle L = 3 × 18 = 54 degrees
Answer:
325 miles to the nearest mile.
Step-by-step explanation:
Average gasoline consumption over the 5 weeks
= miles travelled / gasoline used
= (198 + 115 + 154 + 160 + 132) / (9 + 5 + 7 + 8 + 6)
= 21.69 miles per gallon.
Estimate of number of miles you can drive on 15 gallons
= 15 * 21.69
= 325 miles.
I'll assume that's
Please let me know if that's wrong.
These are two lines in point slope form. They'll meet at some x that makes the ys equal.
is the only solution.
Exactly one solution.
We really only had to ensure the lines had two different slopes. Then there's always exactly one solution.
If the lines had the same slope, they're either the same line (coincident) so an infinite number of solutions, all the points on that line, or they're parallel, no solutions.
Answer: 5√2
Let’s say A(-5,-3) and B(2,-4)
AB= sqr (xB-xA)² + (yb-yA)²
= sqr [2-(-5)]² + [-4-(-3)]²
= sqr 49 + 1
= sqr 50
AB= 5 sqr 2
(sqr=square root)
