328

Step-by-step explanation:

To find the lenght of the far left side use SOH, CAH, TOA

we have the hypotonouse and need the opposite side so we'll use SOH

sin(38)=x/26

26sin(38)=16

Then use pathagoreyous theroem to solve for the last side

a²+16²=26²

a= 20.4882

Then the area is just length*width so

16*20.4882=327.9599 which rounds to 328

Solution given:

we have

sin 38=opposite/hypotenuse

opposite=breadth [w=b]=sin38*26=16

by using Pythagoras law

l²+b²=26²

l²=26²-16²

l=√420

l=20.5

now

Area =l*w=20.5*16=328cm²

here's a poem i finished a while ago. i hope you like it and that it inspires you.

step-by-step explanation:

f(gx)=f(1/x+2)

=(1/x+2)+2

=(1+2x)/2+2

=(1+2x+4)/2

= (2x+5)/2
