Question

Find the missing values. Leave answers in simplified radical form.

Answer 1

#3

• tan45=8/t
• 1=8/t
• t=8

Simiilary

• cos45=8/r
• r=8√2

#4

• sin60=9√3/f
• √3/2=9√3/f
• 1/2=9/f
• f=18

And

• cos60=0/18
• 1/2=0/18
• o=18/2=9

Answer 2

See below ~

Explanation:

Q3

• r = 8 / sin 45°
• r = 8 / (1/√2)
• r = 8√2

• t = 8 / tan 45°
• t = 8 / 1
• t = 8

Q4

• f = 9√3 / sin 60°
• f = 9√3 / (√3/2)
• f = 18

• o = 9√3 / tan 60°
• o = 9√3 / √3
• o = 9
