I need help with this ASAP pleasee

a = 2

b = 2√2

════════════════════

Opposite = 2√2

════════════════════

Adjuscent = ?

Hypotenuse = ?

════════════════════

•Finding a - hypotenuse

# Use sin formula

sin(∅) = opposite / hypotenuse

sin(45) = 2√2 / hypotenuse

hypotenuse = 2√2 : sin(45)

hypotenuse = 2

•Findinf b - adjuscent

# Use tan rule

tan(∅) = opposite / adjuscent

tan(45) = 2√2 / adjuscent

adjuscent = 2√2 : tan(45)

adjuscent = 2√2

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
