Answer:
83 %
Step-by-step explanation:
If 5 out of 30 got an A, that means that
30 -5 = 25
25 out of 30 did not get and A
25/30 = .8333333 = 83.33333 %
Rounding to the nearest whole percent
83 %
Answer:
BC=
Angle A (or BAC)=54.31466...
Angle C (or ACB)=35.68533...
Step-by-step explanation:





We notice from the choices, that the problem is solved using the Pythagorean theorem somehow. How?
If ABC was a right triangle, the hypotenuse would be BC (the largest side), so the right angle would be A.
In that case we would have 54 squared (which equals 2916) equal to the sum of the squares of 22 and 51 (which equals 3085).
If the triangle was a right triangle,

would be exactly equal to

, but it is larger. This means that a right angle is not large enough to 'enclose'

. Thus angle A must be opened more that 90°.
Thus the answer is D:
an obtuse triangle because
Answer:
x=127 degrees
Step-by-step explanation:
look at the image also it's 127 not 117
