Answer:
They are supplementary
Step-by-step explanation:
Since AB and DC are parallel, then the alternate interior angles are congruent because there is transversal cutting the parallel lines (BC). So m<B is supplementary to m<C
A) 65%
b) 68
26:40 as x:100
26/40 = x/100
Cross multiply
2600 = 40x
x = 65
———————
85% of 80
0.85 is the decimal equivalent of 85%
80 x 0.85 = 68

more interest earned=2500×1×3/2×1/100=37.50$
Answer:
where 
Step-by-step explanation:
given equation is:
since no range is provided we can solve for all values of 
:
for one cycle of cos 
for all cycles of cos
we should also include negative values.
we can divide each value by 2, to get the solutions for instead of 
Answer:
This is the solution of the equation .
In its most general form we can write all solutions of the equation in terms of 
where or n is an integer.
