A triangle's angle measures add up to 180°.
67 + 90 = 157
180 - 157 = 23
The last angle measure is 23°.

The longer the side length, the larger the angle opposite it is. And vice versa. The shorter the side length, the smaller the angle opposite it is.

Side Length: ∠ Measure Opposite Side:
5 in 23°
12 in 67°
13 in 90°

Find the total surface area of the cone in the figure. ( use rr=3.14.)

nikitadnepr [17]

Answer:

Answer D

Step-by-step explanation:

The formula is $A = pi r(r+\sqrt{h^2+r^2})$ . We have our r (radius) and h (height), so plugging it all in would give us A = (3.14)(5 + sqrt(12^2)+(5^2). After computing this, you would get answer D, 282.6.

In Exercise,find the balance in the account after 10 years.

djverab [1.8K]

Answer: The balance in the account after 10 years is $3374.65

Step-by-step explanation:

The exponential equation for growth [ compounded continuously] is

$y=pe^{rt}$

, where P= Present value

r= growth rate ( in decimal)

t= time (years)

By considering the given information , we have

p=$2500 r = % =0.03 and t= 10

Substitute all the values in the above equation , we get

$y=2500e^{0.03(10)}$

$y=2500e^{0.3}$

$y=2500(1.3498588)=3374.64701894\approx3374.65$ [Round to the nearest cent]

Therefore, the balance in the account after 10 years is $3374.65
