Answer:
Step-by-step explanation:
Judging by the context, you are looking for the angle x of a triangle, where the other two angles are 76 and 49. The sum of a triangle's angles is always 180, so
76 + 49 + x = 180
125 + x = 180
x = 55
Answer:
4(x^2)(y^0)
Step-by-step explanation:
or 4(x^2) either one should be correct
Answer:
C. 2 units
Step-by-step explanation:
The ratio of side lengths in an isosceles right triangle is ...
1 : 1 : √2
If you don't already have this memorized, you can figure it out using the Pythagorean theorem:
BD² = AD² +AB² = 1 + 1 = 2
BD = √2 . . . . taking the square root
__
We are told that BD = DC, so we know the larger triangle is also an isosceles right triangle. This one has short sides of length √2, so the long side (BC) will have length (√2)×(√2) = 2.
The length of BC is 2 units.

Answer: True</h3>
More specifically, these two triangles are congruent by the SAS congruence theorem. SAS stands for Side Angle Side.
- The first "S" is the pair of sides that have double tickmarks
- The "A" refers to the congruent vertical angles
- The second "S" is the pair of sides that have triple tickmarks
