Answer:

The difference in temperature is 105 degrees.

Step-by-step explanation:

The difference in temperature is 105 degrees because it's -20 in Alaska and 85 in Hawaii. When calculating the difference in temperature, negative numbers are still added to the sum total. so 85 + 20 = 105.

the perimeter of an equilateral triangle is 39 centimeters. What is the length of an altitude of the triangle ?​
victus00 [196]

Answer: h = 11.26cm

Step-by-step explanation:

Equilateral triangle has equal sides, let the side be xcm , then the perimeter is 3x

Therefore:

3x = 39

x = 39/3

x = 13cm

To find the altitude , we will apply Pythagoras theorem , that is

13^{2}=h^{2}+6.5^{2}

Therefore:

h^{2}=13^{2}-6.5^{2}

h^{2}=169-42.25

h^{2}=126.75

take the square root of both sides

h = 11.26cm
