Answer:
#1 is 60°, #2 is 55°
Step-by-step explanation:
all angles in a triangle add up to 180° so u can just subtract from that for the missing angles. :)
Answer:
An airplane cruises 1 kilometer in 1/12 of a minute. What is its cruising speed?<u>200</u>
The <em>correct answer</em> is:
interpolating
Explanation:
Interpolation is a method of constructing new data points within the range of a discrete set of known data points.
This would include inserting data points between two known points and extending a data set.
The answer is 14 plants.
Explanation:
She already has 4 plants. She adds 9 more plants to the 4 plants. She will have 13 plants. And then she adds 1 plant to the 13 plants. She has now 14 plants.
Hope it helps!
Since the product of the slope is -1, hence the lines are perpendicular
<h3>Parallel and Perpendicular lines</h3>
Two lines are known to be parallel if they have the same slope while if two lines are perpendicular if the product of the slope is -1
Given the coordinates of line 1 passing through (0, 6) and (6, 4), the slope is given as;
Slope = 4-6/6-0
Slope = -2/6
Slope = -1/3
Similarly for the coordinate points (-1, -7) and (1, -1).
Slope = -1+7/1+1
Slope of line 2 = 6/2
Slope = 3
Take the product of the slopes
Slope = -1/3 * 3
slope = -1
Since the product of the slope is -1, hence the lines are perpendicular
