X^2 + 9y^2 = 25
x^2/5^2 + (3y)^2/5^2 = 1
This represent an equation of an ellipse with cente at the origin, the horizontal major axis running from -5 to 5 and vertical minor axis running from -5/3 to 5/3
The third graph is the correct answer.
Answer:
The fox; 23 miles per hour
Step-by-step explanation:
An acute angle is <90 degrees
a right angle is equal to 90 degrees
an obtuse angle is >90 degrees
Any triangle has angles adding to 180 degrees
therefore three acute angles, eg. 60, 60 and 60 degrees can make up a triangle
2 acute angles and a right angle, say 45 and 45 degrees and 90 degrees make a triangle
any obtuse angle + a right angle will be larger than 180 degrees, so no triangle can exist. another acute angle will make the number of degrees even larger
any 2 obtuse angles will make a number larger than 180 degrees, so with an acute angle is impossible
2 acute and an obtuse angle is possible, say 40, 40 and 100 degrees
Answer:
perpendicular
Step-by-step explanation:
They form a 90 degree angle
