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°
The answer is Y=-2/5x+1 :)
Answer:
$7600
Step-by-step explanation:
total income = 120,000(.06)+100(4)
total income= 7200+400
total income = 7600
.
Step-by-step explanation:
-b/2a
a=-6 and b=6
-(6)/2(-6)
=1/2 or 0.5
