i think it is because...
the slope of line b is slightly steeper than the slope of line a.
hope this helps!
Answer:
8.7°
Step-by-step explanation:
The above problem can be represented by a right angled triangle with height of 7 m, hypotenuse = AB.
The base of the triangle is gotten by finding the diagonal of the road. That is using Pythagoras theorem:
base² = 43² + 15²
base² = 2074
base = 45.54 m
Using trigonometric function to find angle A:
tan(A) = base / height
tan(A) = 45.54 / 7
tan(A) = 6.506
A = tan⁻¹ (6.506)
A = 81.3°
Angle of depression = 90° - A = 90 - 81.3
Angle of depression = = 8.7°
Answer:
b.-5
Step-by-step explanation:
Whatever you do to one side you do to the other
You multiply the number outside the parenthesis with both of the numbers in the parenthesis separately.
Answer:
1st option: G, H, I
Step-by-step explanation:
Collinear points are points that lie on the same straight line.
In the diagram, the collinear points are:
• L, H, J
• G, H, I, K
For the 2nd option, I does not lie on the same straight line as L and H.
For the 3rd option, J does not lie on the same straight line as G and H.
For the 4th option, J does not lie on the same straight line as G and I.
Thus, the 2nd, 3rd and 4th options are incorrect.
