An acute angle θ is in a right triangle with sin θ = seven eighths. What is the value of cot θ?

olga2289 [7]

Draw a right triangle ABC, with m(CAB)=∅.

Let CB=7 units, AC=8 units, so by the Pythagorean theorem:

$AB= \sqrt{ AC^{2} - BC^{2} }= \sqrt{ 8^{2} - 7^{2} }= \sqrt{64-49} = \sqrt{15}$ (units)

so we have drawn a triangle where sin∅=7/8

in this triangle, cot∅=(adjacent side)/(opposite side)= $\frac{ \sqrt{15} }{7}$

Answer: <span>square root of fifteen divided by seven</span>

AABC is a right triangle. If AC = 15 and BC = 17, find AB.

Schach [20]

Answer:

AC=15

BC=17

AB=?

According to Pythagore's Theorem: AB² + AC² = BC².

AB² = BC² - AC²

= (17)² - (15)²

= 289 - 225

AB² = 64

AB = √(64)

= 8.

So AB = 8.
