Answer: 40°
Step-by-step explanation: The formula for calculating the size of an exterior angle is: exterior angle of a polygon = 360 ÷ number of sides. So it's 360°÷9=40°
The answer should be, b = 1
Answer:
240
Step-by-step explanation:
fifteen lots of sixteen = 15x16
15x16=240
The limit is presented in the following undefined form:

In cases like this, we can use de l'Hospital rule, which states that this limit, if it exists, is the same as the limit of the derivatives of numerator and denominator.
So, we switch

The derivative of the numerator is

Whereas the derivative of the denominator is

So, the new limit is

So, it would seem that we didn't solve anything, but indeed we have! Recall the limit

to conclude that the limit converges to \dfrac{6}{25} [/tex]
Area = 1/2 x base x height
Let the height be x.
Height = x
Base = 2x
Area of triangle = 1/2 x base x heght
Plug base and height into the variables:
(1/2)(2x)(x) = 196
Combine like terms:
x² = 196
Square root both sides:
x = 14
Find Base and height:
Base = x = 14 km
Height = 2x = 2(14) = 28 km
Answer: Height = 28km
