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
Since both lines c and b are perpendicular to line a, line c and b are parallel.
Using the two points on line b, we can count “up 5, right 5” to find the slope of line b to be 5/5 or 1.
Since line b has a slope of 1 and line c is parallel, it must also have a slope of 1.
Answer:
x=2
Step-by-step explanation:
2.5(6x-4)=10+4(1.5+0.5x)
Distribute
15x -10 = 10 + 6 +2x
Combine like terms
15x -10 =16+2x
Subtract 2x
13x -10 = 16
Add 10
13x= 16+10
13x = 26
Divide by 13
13x/13 = 26/13
x =2
