So first write out the expression:
take two 10's from the top to cancel with the two 10's on the bottom.
3.9/1.3 is 3.
The answer is 3*10^3
Answer:
Angle y and Angle x are complementary angles
Step-by-step explanation:
we know that
If
sin(y°)=cos(x°)
then
Angle y and Angle x are complementary angles
so
∠y+∠x=90°
∠x=90°-∠y
sin(y°)=cos(90°-y°)
therefore
The sine of an angle is equal to the cosine of its complementary angle
A heptagon has 7 sides.
Sum of all interior angles = (7 - 2) x 180 = 900°
900 - 776 = 124°
Answer: The final angle must be 124°
Answer:
60
Step-by-step explanation:
We can easily solve this by finding out how many 60 seconds are in 10 minutes, and then dividing by 10.
To do that, multiply 60 seconds by 10, since there are 60 seconds in each minute.
60*10=600. There are 600 seconds in ten minutes.
Now, divide by 10.
600/10=60
There are 60 intervals of 10 seconds in 10 minutes.
Hope this helps!
