In ΔFGH, f = 35 inches, g = 20 inches and h=30 inches. Find the measure of ∠H to the nearest degree.

9514 1404 393

  59°

Step-by-step explanation:

The law of cosines tells you ...

  h² = f² +g² -2fg·cos(H)

Solving for angle H gives ...

  H = arccos((f² +g² -h²)/(2fg)) = arccos(725/1400) ≈ 58.811°

  ∠H ≈ 59°

lol, i have been using this product for a while and the second half of the year for a lon and the first time in a long time ago that the government has not yet received enough votes to be a good the first place in the world to be able to do it in my world life, i

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
