Answer:
a). ∠D = 56°
b). AD = √13
Step-by-step explanation:
(a) From the figure attached, ABCD is a trapezoid with parallel sides AB and CD. We have to find the measure of ∠D from the given figure.
From triangle ADE,


D = 
D = 56.31
D ≈ 56°
Therefore, measure of ∠D is 56°.
(b). Now by applying Pythagoras theorem in ΔADE,
AD² = AE² + DE²
= 3² + 2²
AD² = 9 + 4
AD = √13
Length of AD is √13 in.
Answer:
D
Step-by-step explanation:
<span>Kayla walks a path with a triangle shape with three corners, starting point A, point where turns north, B, and point where head towards start, C.
The question is calculate the angle in the point C, knowing that A-B distance is 4 km and B-C is 2.5
To do this calculation we are going to use the trigonometry function tangent:
tangent C = opposite/adjacent = 4/2.5 = 1.6
Then C angles is: C = arctan (1.6) = 57.99Âş
So the solution is round to 58Âş</span>
A. 6 and b. 12. You take 3.6 and divide it by .6 then multiply by 2 for the second answer
