It would surely be helpful if you let us know which angles to measure!
Eight with the decimal numbers of eight hundred twenty-five.

Answer:
3. PR=51
4. FE=28
Step-by-step explanation:
3. since the two triangles are similar, set up a proportion:
x+8/3x-9=24/28
*cross multiply*:
28(x+8)=24(3x-9)
28x+224=72x-216
44x=440
x=20
to find PR:
PR=3x-9
PR=3(20)-9
PR=51
4. same here:
39/4x+2=42/5x-2
39(5x-2)=42(4x+2)
195x-78=168x+84
27x=162
x=6
to find FE:
FE=5x-2
FE=5(6)-2
FE=28
Answer:
50
Step-by-step explanation:
An angle that measures 50° Turns through 50 1° angles because 50 *1 = 50
1 degree * 50 turns = 50 degrees
