What is the tangent of ∠qtr if line pr is tangent to circle t at q, and ts = 1 cm?
a) tq
b) uq
c) tr
d) rq

D) RQ

Step-by-step explanation:

The mnemonic SOH CAH TOA tells you the relation for the tangent of an angle in a right triangle is ...

Tan = Opposite/Adjacent

For angle QTR, the Opposite side is RQ and the adjacent side is TQ Then the tangent is ...

tan(∠QTR) = RQ/(1 cm) = RQ . . . . . for RQ expressed in centimeters

Comment on units

The tangent of an angle is a ratio of two distances, so is a unitless quantity. Strictly speaking, RQ has units of length, so the best you can say is that when RQ is expressed in centimeters, the numerical value of the tangent of the angle is the same as the numerical value of the length of RQ.

theresa talked her parents into getting sd cards for her phone and her brother’s phone. inserting an sd card into a phone gives it more storage. they both get 8-gigabyte sd cards. how many bits of storage come with each sd card? type your answer in both scientific and standard notation.

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
