Answer:
300tan43 - 300tan40
Step-by-step explanation:
Use tangent to find the height of the building:
tan40 = b/300
b = 300tan40
The use tangent to find the height to the top of the antenna:
tan43 = a/300
a = 300tan43
The antenna height = a - b
Answer:
-437
Step-by-step explanation:
Substitute the knowns into 12x−3y4x−z
12x = 12*3 = 36
3y = 3*13 = 39
4x=4*3 = 12
z=5 = 5
So, 36-(39*12)-5 = -437
Answer:
Quadrilateral
Step-by-step explanation:
Any shape with 4 side and angles is classified as a quadrilateral
Answer:
Option C) 4 congruent sides
Step-by-step explanation:
From the construction done as per statements given in the question.
AB is a common radius of circles A and circle B.
Since AB = AC = AD ( radii of circle A)
And AB = BC = BD (radii of circle B)
Therefore, AB = AC = AD = BD = BC
All sides of quadrilateral ABCD are equal.
Option C is the answer.
