Answer:
Step-by-step explanation:
<u>Use the Pythagorean theorem:</u>
<u>Verify this for each line:</u>
1.
- 28² + 45² = 53²
- 2809 = 2809
- Yes
2.
- 33² + 56² = 64²
- 4225 ≠ 4096
- No
3.
- 36² + 77² = 85²
- 7225 = 7225
- Yes
Basically, shift each coordinate one unit to the right (one X over)
You will have to predict the points a little
Step-by-step explanation:
in isoscles triangles two angles and lengths are equal .
two sides equal 3.5
so both of the angles are 55°
the sum of the angles in a triangle is 180°, so
x = 180° - 55° - 55°
x = 70° (Ans)
The final answer that i got from this was -x-13
