Answer 1

In , is C a right angle. Find m<B to the nearest tenth of a degree.

Answer 2

algebra unit test hmm....

Answer 3

quiz, it just shows as a test -- checking answers!

Answer 4

B is the one with an x right?

Answer 5

yes

Answer 6

given that they give you all 3 measures of sides; you can take your pick from any of the tangent inverse functions

Answer 7

21.8 degrees
(180 ArcTan[24/60]/\[Pi])

Answer 8

perhaps like?:

tan(x) = 24/60

x = tan-1(2/5)

Answer 9

\[(180 \text{ArcTan}[24/60]/\pi ) \]

Answer 10

if your calculator is already set up in degrees; robs will be off.

Answer 11

if in radians, mine will be off :)

Answer 12

test it by sin(90); it should be 1

Answer 13

put your calculator in degree mode first so you don't need to mess around with any conversions

Answer 14

then you have a plethora of options. you can compute
\[\tan^{-1}(\frac{24}{60})\]
\[\sin^{-1}(\frac{24}{64.6})\] or even
\[\cos^{-1}(\frac{60}{64.6})\]
