Answer:
perpendicular
Step-by-step explanation:
First we need to dtemine the slopes of the line
For line 1
L1: (-4, 6) (-3,-1)
m1 = y2-y1/x2-x1
m1= -1-6/-3+4
m1 = -7/1
m1 = -7
For line 2:
L2: (8,9) (15, 10)
m2 = 10-9/15-8
m2 = 1/8
Take their product
m1 * m2 = -7 * 1/7
m1m2 = -1
Since the product of their slopes is -1, hence they are perpendicular
The two triangles BQA and DQC are similar triangles. The ratio of corresponding sides of similar triangle is the same.
So, we can write:
BQ : BA = DQ : DC
15 : 32 = DQ : 19.2
⇒
32 * DQ = 19.2 * 15
DQ = 9
We are to find the length of BD.
BD = BQ + QD = 15 + 9 = 24
So the answer to this question is 24
Answer:
21.8 m
Step-by-step explanation:
The tangent function relates this angle, height and horizontal distance:
height
tan 23.6 degrees = --------------
50 m
Then the height of the building is (50 m)(tan 23.6 degrees) = 21.8 m
