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:
The total cost of the bike is $180.
Step-by-step explanation:
Given that Juanita has saved 35% of the money for a bike.
Let the total cost of the bike = x
As she has saved $63 dollars which represents the 35% of the money for a bike.
In other words, 35% of the total cost is $63 dollars.
As the total cost = x
Thus,
35% of x = 63
Multiply both sides by 20
simplify
Divide both sides by 7
Simplify
$
Thus, the total cost of the bike is $180.
