Answer:
units²
Step-by-step explanation:
D and E lie on the x- axis and F is vertically below D
The triangle formed is right at D with legs of length 3 and 7
The area (A) of a right triangle is found using the formula
A = bh ( b is the base and h the perpendicular height )
here b = 3 and h = 7, hence
A = × 3 × 7 =

Answer:
θ = 27.47°
Step-by-step explanation:
This problem can be represented as a right-angled triangle, as shown in the diagram below.
To find θ, we apply the tangent part of the trigonometric ratios SOHCAHTOA:
tanθ =
In the diagram, opposite = 1.3 m and adjacent = 2.5 m
Hence:
tanθ =
tanθ = 0.52
θ =
θ = 27.47°
The ramp forms 27.47° with the ground.
