Answer:
14 degrees
Step-by-step explanation:
This because if you take away 10 degrees, that would get you to 0 degrees. The subtract 4 degrees more and that would give you 14 degrees.
5/8 = x/9
cross multiply
8x = 5 * 9
8x = 45
x = 45/8
x = 5.625....rounds to 5.6
So to get the mean, you need to work out the sum of the values and divide it by the number of values there are.
This means you should do:
(Let x represent the fifth score)
(92 + 85 + 90 + 92 + x) / 5 = 90
(92 + 85 + 90 + 92 + x) = 450
359 + x = 450
x = 450 - 359
x = 91
So the answer is 91 and you are correct :)
Answer:
Isosceles Triangle; Acute Triangle
Step-by-step explanation:
Review your definitions of the different types of triangles:
acute triangle- a triangle that has three acute (less than 90 degrees) angles
obtuse triangle- a triangle that has an obtuse (greater than 90 degrees) angle.
right triangle- a triangle that had one right (90 degrees) angles
isosceles triangle- a triangle with two congruent sides and one unique side and angle.
equilateral triangle- a triangle with three congruent sides and three congruent angles.
scalene triangle- a triangle with no congruent sides and no congruent angles.
With these definitions, we can classify ΔPQR as an isosceles acute triangle.
