Answer:
A. sec =12/13×
B. COS =12/13×
C. tan =12/5✓
D. sin =12/13 ✓
Step-by-step explanation:
we know,
using Pythagoras formula,
p=12,h=13 ,b=?
h^2 =p^2 +b^2
b=5
so tan = p/b
=12/5
sin=p/h and cosec= h/p
D. sin =12/13
Answer:
x=4
Step-by-step explanation:
5x-4=16
5x-4+4=16+4 add 4 to each side
5x=20 simplify
5x/5=20/5 divide each side by 5
x=4 simplify
Step-by-step explanation:
✧ 
- Set up an equation and solve for x :
⋆ 
[ Exterior angle is always equal to the sum of two non - adjacent interior angles ]
~Remove the unnecessary brackets
⟶ 
~Add the like terms : 2x ° & 3x°
⟶ 
~Move 4x to right hand side and change it's sign
~Similarly move 12 to left hand side and change it's sign
⟶ 
⟶ 
⟶ 
- Now , Substituting the value of x in (4x+9)° [ Exterior angle ]

Given that :-
→ N represent the number of bikes .
→ Weight of container including bikes is 250+23(n-1) pounds.
To Find :-
→ Weight of container when we have 20 bikes.
Solution :-
→ Weight = 250+23(n-1) pounds
Putting the value of n here .
→ Weight = 250+23(20-1)
→ Weight = 250 +23(19)
→ Weight = 250 + 437
- → Weight of container is 687 pounds.
The answer would be the 1st graph, or more specifically, the graph which has the lines intersecting at coordinates (-4,-3)
