F=3/5x^2-3x+18/5 is the answers
Answer:
AT = 8
Step-by-step explanation:
Using the sine ratio in the right triangle
and sin45° = 
sin45° =
=
= 
Multiply both sides by AT
AT × sin45° = 8, that is
AT ×
= 8
Multiply both sides by 
AT = 8
I think it's x2 I'm not sure plz don't trust me
- given
- distributive property (we distributed the 3)
- sum like terms (we summed 28 and 6)
- addition property of order (we summed 3x to both sides)
- subtraction property of order (we subtracted 10 to both sides)
- division property of order (we divided both sides by 8)
