Step-by-step explanation:
sin 25 = 15 / xz
xz = 15/ sin 25
xz = 35.49
tan w = 35.49 / 22
w =58.15
Answer:
Step-by-step explanation:
For each right-angled triangle:
Because
we have an equation
multiplying both sides by x, we get
dividing both sides by 0.4 and
using calculator, we divide 12 by 0.4
and finally x=30
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
Isolate the variable y
The solution is the shaded area below the solid line
Is below because the symbol of the inequality is less
Is a solid line because the line is included in the solution
The equation of the solid line is
To graph the solution find the intercepts
Find the x-intercept (value of x when the value of y is equal to zero)
For y=0, x=6 --------> point (6,0)
Find the y-intercept (value of y when the value of x is equal to zero)
For x=0, y=2 -------> point (0,2)
Graph the inequality
see the attached figure
