Answer:

2.6 feet

Step-by-step explanation:

The length of the base can be found using Pythagoras theorem.

Let the let of the base be represented as y

Given

The left side = 3 feet

Right side = 4 feet

Therefore 4^2 = 3^2 + y^2

4 x 4 = 3 x3 + y^2

16 = 9 + y^2

Subtract 9 from both sides

16 - 9 = 9 - 9 + y^2

7 = y^2

Or

y^2 = 7

y = squared root of 7

y = 2.6 feet

The length of the base is 2.6 feet

Also given that the relation betweeen the australian and american currency is y = 1.03x where y is the amount in australian currency and x is the amount in the american currency.

Now we have x= 118.

y=1.03\times118=121.54

Points D and E are midpoints of the sides of triangle ABC. The perimeter or the triangle is 48 units. What is the value of t?
Komok [63]

Answer:

2 units

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. Types of triangle are acute, obtuse, scalene, isosceles, equilateral and right angled triangle.

Since point D and E are midpoints of the sides of triangle ABC, hence:

AD = BD = 3t, BE = CE = 4t, AC = 7t + 6

The perimeter of triangle ABC = AC + BC + AB = AC + AD + BD + BE + CE;

Substituting:

48 = 7t + 6 + 3t + 3t + 4t + 4t = 21t + 6

48 = 21t + 6

21t = 42

t = 2 units
