5x+(-20)=-15x and there you have it
Answer:
≈ 50.7 cm²
Step-by-step explanation:
The area (A) of Δ XYZ is calculated as
A =
bh ( b is the base and h the perpendicular height ), that is
A =
× XY × YZ
Calculate YZ using the tangent ratio in the right triangle
tan40° =
=
=
( multiply both sides by 11 )
11 × tan40° = x , that is
YZ ≈ 9.23 cm
Thus
A =
× 11 × 9.23 = 5.5 × 9.23 ≈ 50.7 cm² ( to 3 significant figures )
