Answer:
The answer is 5 ft.
Step-by-step explanation:
First, Darla measures 3 ft from the corner along one edge: let’s assume the measurement is from west (corner A) to east (new corner B).
Second, Darla measures 4 ft from the corner along the other edge: the measurement is from the new corner B, northwards to another new corner C.
The length of the diagonal will be the distance between corner A and new corner C = hypotenuse = x
.
We know that if the corner is a right angle corner, then we will have a right-angled triangle where the square of the hypotenuse = sum of the squares of the opposite and adjacent sides:
the adjacent side = 3 ft
the opposite side = 4 ft
Therefore, x² = 3² + 4² = 25
x = square root of 25 = 5 ft
Length of the diagonal = x = 5 ft
.
Answer:
Step-by-step explanation:
∠ABC + ∠CBD = 90 so filling in the expressions for these angles:
(2x + 14) + (x + 7) = 90 and
3x + 21 = 90 and
3x = 69 so
x = 23. To find the measure of angle ABC in particular, we sub in a 23 for x:
x + 7 --> 23 + 7 = 30°, the last choice there.
