Practice problem
You know that c=a2+b2c=\sqrt{a^2+b^2}c=a2+b2. You also know that b=d+fb=\sqrt{d+f}b=d+f. Solve for aaa.
a=c−d−fa=c-\sqrt{d-f}a=c−d−f
a=c2−d2−f2a=\sqrt{c^2-d^2-f^2}a=c2−d2−f2
a=c2−d−fa=\sqrt{c^2-d-f}a=c2−d−f
a=c2−d+fa=\sqrt{c^2-\sqrt{d+f}}a=c2−d+f
Type a concept, like “slope” or “photosynthesis”.
