Answer: isosceles
Step-by-step explanation:
By the alternate interior angles theorem, 
Since angles in a triangle add to 180 degrees, 
Since sides opposite equal angles in a triangle are equal, 
.
So, triangle ABC is <u>isosceles</u>
62 + x = 82
Subtract both sides by 62.
x = 20.
Y = 180 - 51 -56 = 73
x = 180 - 73 - 72 = 35
x = 35 degrees

Answer:
2. D
3. B
4. D
5. A
Step-by-step explanation:
2. Write the ratio using the given words, then fill in the corresponding numbers. Factor out the greatest common factor.*
soccer players : volleyball players = 84 : 36 = 12·7 : 12·3 = 7 : 3
__
3. The <em>angle bisector</em> has angle marks on either side of it. The only angle marks are at angle G, where GL is the bisector.
__
4. The <em>median</em> is drawn from a vertex to the midpoint of the opposite side. The only side with a midpoint marked is IG with midpoint J. The median is HJ.
__
5. An altitude is drawn from a vertex to the opposite side, where it meets at right angles. Two right angles are shown: at J and at K. The perpendicular line at J does not meet any vertex. The perpendicular line at K meets vertex I, so KI is the altitude.
_____
* For larger numbers, or ones whose factors you aren't familiar with, it can be useful to know Euclid's method for finding the greatest common factor (GCF). Divide the larger number by the smaller and keep the remainder. If the remainder is 0, the smaller is the GCF. If not, replace the larger number with the remainder and repeat.
Here, that looks like ...
84 / 36 = 2 r 12
36 / 12 = 3 r 0 . . . . . 12 is the GCF
I believe the answer is A because the square root of 10 root 3 is approximately 17.32.
