Answer:
D. 50°
Step-by-step explanation:
We know that there are 3 line segments that are forming the angles. Based on that, we can safely say that each line segment is 180°. Given that, we can find the other 2 interior angles of the triangle. We know that one of the exterior angles is 90° so that interior angle also has to be 90° because both angles have to sum to 180. The 2nd exterior angle that we know is 140, so 180-140 = 40°. Since we know the other 2 angles of the triangle now and we know that all the angles of a triangle must sum to 180°, we add 90 and 40 to get 130 and then subtract that from 180 to get 50°. That would look something like this: 180-(90+40) = 180 - 130 = 50°. Hope this helps!
Answer:
Correct choice is C
Step-by-step explanation:
Let x be unknown number.
Three times a number x is
Three times a number is no less than negative six means that the number can be equal to -6, can be greater than -6, but cannot be less than -6.
Thus, the inequality that could be used to solve the problem is
Answer:
Only first two are exponential growth function and last three functions are exponential decay functions.
Step-by-step explanation:
We need to describe exponential growth or decay for the given functions.
The standard exponential function equation is
Where a is the initial value and b is the growth factor.
Note: If value of b > 1, it would be an exponential growth and if b < 1, it would be an exponential decay.
Value of b is 1.008 > 1, therefor it's an exponential growth function.
y=250(1+0.004)^t, also have b>1 therefor it's an exponential growth function.
All other functions has b values less than 1, therefore only first two are exponential growth function and last three functions are exponential decay functions.
Looks like 49 and w complete the 77 angle
77-49 = w
W= 28
