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 )
Answer:
14×6=84 and 6×14=84, 84+6=90
Answer:
(2, -9)
Step-by-step explanation:
2 - (-9) > 8 First, substitute the values for x and y.
2 + 9 > 8
11 > 8 The inequality is true, so (2, -9) is the correct pair.
