How do you find the area of each triangle?

Mathematics

There's a big triangle with base (2+6) meters and altitude 5 meters.

The formula for the area of a triangle of base B and altitude H is

A = BH/2.

The area of the large triangle is thus A = (8 meters)(5 meters)/2, or 
20 square meters.

Use A = BH/2 to find the areas of the other triangles.

Step-by-step explanation:

Given data

diagonal of the TV d= 55in

Widht of the TV w=  42 in

d^2= w^2+ h^2

substitute

55^2= 42^2+ h^2

3025= 1764+ h^2

3025+1764= h^2

What is 3/4 ÷ 1/6? Please help !......
Reika [66]

Answer:

4 1/2

Step-by-step explanation:

Apply the fractions formula for division, to

3/4÷1/6

and solve

3/6x4/1

=18/4

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(18,4) = 2

18/24÷2/2=9/2

Convert to a mixed number using

long division for 9 ÷ 2 = 4R1, so

9/2=4 1/2

Therefore:

3/4÷1/6=4 1/2
