3. ΔBDE ~ ΔBCF
4. BF/BC = BE/BD
5. 254/BC = 160/457
.. BC = 254*457/160 ≈ 725 units
Answer:
65°
Step-by-step explanation:
If you add all the angles in a triangle, they equal 180°. You can subtract given angles to find missing angles.
Let's first subtract 25° from 180°. 180° - 25° = 155°.
This is a right triangle, so we know there is also a 90° angle. Also subtract this. 155° - 90° = 65°.
We are left with 65°. This is the measure of the third angle.
The triangle's angles are, 25° ; 90° ; 65°
The answer to the problem is 8 2/3.

Answer:
(X,Y)(18,12)
Step-by-step explanation:
x + y = 30
2x + 4y = 84
___________
2x+2y=60
2x+4y=84
_________
-2y=-24/-2y
y=12
2x+4(12)=84
2x+48=84
2x=84-48
2x/2=36/2
X=18
