In ΔRST, r = 71 cm, � m∠T=48° and � m∠R=37°. Find the length of t, to the nearest 10th of a centimeter.

Answer:

t/sin T = r/sin R

where T and R are the measures of the opposite angles of t and r, respectively.

First, we need to find the measures of T and R in radians:

T = 48° * pi/180 = pi/4

R = 37° * pi/180 = 37 * pi/180

Next, we can use these values in the formula:

t/sin T = r/sin R

t = r * sin T / sin R

t = 71 * sin(pi/4) / sin(37 * pi/180)

Using a calculator, we can estimate t to the nearest 10th of a centimeter:

t ≈ 107.9 cm

So the length of t is approximately 107.9 cm to the nearest 10th of a centimeter.
