Is the height of an equilateral triangle the same as the sides?

Hoochie [10]

No,
although all the sides are the same length on an equilateral triangle the height is calculated by a straight perpendicular line at the mid point of the base.

The sides are not perpendicular with the base and are angled outwards

3/4√5-√3 + 2/4√5+√3 =b√3+a√5 find the value of b and a

Zielflug [23.3K]

Answer:

a = 5 / 4

b = 0

Step-by-step explanation:

3/4√5 - √3 + 2/4√5 + √3 = b√3 + a√5

3/4√5 + 2/4√5 + √3 - √3 = b√3 + a√5

5/4√5 + 0 = b√3 + a√5

0 + 5/4√5 = b√3 + a√5

b√3 = 0

b = 0 / √3

b = 0

a√5 = 5/4√5

a = 5/4√5 / √5

a = 5 / 4

What the answer fast

Dominik [7]

To solve this problem, first let x=0.933333(repeating). Then, you want to multiply both sides by 10 to get 10x = 9.33333 (repeating). Next, take equation 2 and minus equation 1 from it giving you 9x = 8.4. Finally, multiply both sides by 10 and you will get 90x = 84. Divide both sides by 90 giving x=84/90. Answer is 84/90. 84/90 can reduce to 14/15.
