Step-by-step explanation:
The height of the equilateral triangle below is 15 units
Let x is the side of the equilateral triangle
Equilateral triangle is divided into to two special right triangles 30-60-90 degree triangles
Height is 15 units
Hypotenuse is x
use the general ratio of 30-60-90
compare the sides and find out hypotenuse x
now replace the value of 'a' for x=2a

Step-by-step explanation:
2^(n+2)=2^12
n+2=12
n=10
Answer: m<D = 30
Step-by-step explanation: In the third step of the problem, it says that E is next to itself and equals 90. However, this is not true. Angle BEA and angle CED are vertical angles and are both equal to 65°. This means that to find the measurement of angle D, subtract 65 and 85 from 180, which equals 30.
