5x-3y=2x-xy solve for x

A forest ranger in a 140-foot observation tower sees a fire moving in a direct path toward the windmill by the lake. The angle of depression to the fire is 3°, and the angle of depression to the windmill is 8°. To the nearest foot, how close is the fire to the windmill?

**Math**

triangle abc has sides a=11 b=13 and c=15. find the sum of the angles supplementary to angles a, b, c

**Math**

Suppose <A is one of the acute angles formed by the line x+2y=6 and the x axis. What is the approximate measure of <A to the nearest degree of <A?

**Chem**

B and D

**CHEMISTRY (WEBWORK)**

Yep. X= 0.1 Ea=0 Y= 0.1 DeltaG=0 Z= 0.1

**UCI webworks Problem 9**

a. v, vi b. iii c. iv d. ii e. i

**UCI Webworks**

Longest constraint distance: CV+ and -OH (i, ii) Highest energy: transition state (iv) Shortest constraint distance: CVOH (iii)

**Chemistry (WebWorks)**

A. iii B. ii C. v D. v or vi (either one works) E. vii F. viii

**CHEMISTRY (WEBWORK)**

Yeah, for part A: It's iii. because that's we answered LUMO for CV (the Lewis acid)in the previous question and that's what the picture looks like on Spartan. iv. is the HOMO for OH (Lewis base found in the previous question also. Part B is i., but dunno how that ...

**chemistry**

CV OH LUMO HOMO

**chemistry(check my answer)**

It's A
