Answer:
Angle of elevation = 21.167°
Step-by-step explanation:
Given:
Horizontal distance cover by rover = 180 m
Vertical distance cover by rover = 65 m
Find:
Angle of elevation
Computation:
Using trigonometry function;
Sin θ = Perpendicular / Hypotenuse
⇒ Sin θ = Vertical distance cover by rover / Horizontal distance cover by rover
⇒ Sin θ = 65 / 180
⇒ Sin θ = 0.3611
⇒ Sin⁻¹ (0.3611) = 21.167°
Angle of elevation = 21.167°
Answer:
a<-4
Step-by-step explanation:
To solve this, you have to isolate a. This means you will have to add 5 to both sides. This will make the equation -2a>8. Divide both sides by 2 to get -a>4. Divide each side by -1 to get a>-4. Because you have to flip the sign when you divide by a negative number, you have to change it into a<-4.

Answer:
200 minutes
Step-by-step explanation:
14 + 0.09 x = 18 + 0.07 x
0.09 x - 0.07 x = 18 - 14
0.02 x = 4
x = 400/2 = 200
Answer:
7 or -9, dependent on if 2y is or is not negative
Step-by-step explanation:
If 2y is NOT negative
2(4)-1=i
8-1=i
i=7
If 2y IS negative
-2(4)-1=i
-8-1=i
i=-9
