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 )
The answer is the first one <3
Answer:
C i think
Step-by-step explanation:
Because length × width × height and when you multiply you get 4.5 or 4 1/2
im so sorry if i'm wrong
First you write out your equation, which is 28x-42=154. Then you solve you equation. First, add 42 to each side, get 28x=196. Divide both sides by 28, get x=7.
