The two "shorter" sides are referring to the legs of the triangles, because the hypotenuse is the largest side. Looking at this, we can find that it's a 3-4-5 triangle, which means that the scaling factor is 3, because 9/3 =3, 12/3=4, meaning we multiply 5 by 3 to get 15.
Answer:
21.99 units
164.93 units²
Step-by-step explanation:
given radius r = 15 units
angle of sector = 84°
Length of sector = x 2 x π x r
= x 2 x 3.14 x 15
= 21.99 units
Area of sector = x π x r²
= x 3.14 x 15²
= 164.93 units²
