Answer:
1.29
Step-by-step explanation:
The diagonals of a kite are perpendicular.
Angles QRT and SRT are congruent.
In right triangle STR, for angle TRS, ST is the opposite leg, and SR is the hypotenuse. The sine ratio relates the opposite leg to the hypotenuse, so we use the sine ratio to find the length of segment ST.
sin <TRS = opp/hyp
sin <TRS = ST/SR
sin 23 deg = ST/3.3
ST = 3.3 * sin 23 deg
ST = 1.29
a) 35 x 13 + 3.14 x 
²
= 455 + 3.14 x 42.25
= 455 + 132.665
= 587.665 m²
∴ The area is 587.665 m².
