Jasper Wrote a formula for the area of triangle RST in terms of only the sides and angles. His steps are shown. Step 1: A =
1: A = 1/2 hs
Step 2: sin(R) = h/r
h = rsin(R)
Step 3: A = 1/2(r)(s)sin(R)

Identify the error in Jasper's work, then replace one term in his equation to write a correct equation for the area.

A= 1/2rs sin(R)

replace r with t

Step-by-step explanation:

correct on plato

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
