Question

a right triangle contains a 28degree angle whose adjacent side measures 10 cm. what is the length of the hypontenus?

Answer 1

Use cosine ratio to find it.
cos 28 = 10 / hypontenus
hypontenus = 10/ (cos28) = ...?

Answer 2

howd you do that?

Answer 3

/ means multiplyy or divide?

Answer 4

You need a trig calculator or a table. Set it up as\[\cos(28^{o})=\frac{10}{h}\implies h=\frac{10}{\cos(28^{o})}\]

Answer 5

/ = divide
