Each side of an equilateral triangle measures 30cm. Find the length of an altitude, a , of the triangle?

Answers

Answer 1

Answer:

[tex]X=25.98cm[/tex]

Step-by-step explanation:

From the question we are told that:  

Length of each side [tex]l=30cm[/tex]

Let the triangle be divide by two form a right angle triangle with base angles as [tex]90 \textdegree[/tex](angle of perpendicularity) and [tex]60 \textdegree[/tex] (angle on each vertices of an equilateral triangle)

Generally the equation for the Altitude X is mathematically given by

Trigonometric Rule

[tex]X=30sin60[/tex]

[tex]X=15\sqrt{3}[/tex]

[tex]X=25.98cm[/tex]

Answer:

- 50

Step-by-step explanation:

x = 3

f ( x ) = - 4x^2 - 3x - 5

f ( 3 )

= - 4 ( 3 )^2 - 3 ( 3 ) - 5

= - 4 ( 9 ) - 3 ( 3 ) - 5

Answer:

Volume = 120 cubic cm

Step-by-step explanation:

We would apply the formula for determining the volume of a square bases pyramid which is expressed as

Volume = 1/3 x base area x height

From the diagram,

length of square base = 6 cm

The base area = 6^2 = 36

height = 10

Thus,

Volume = 1/3 x 3/6 x 10

Volume = 120 cubic cm

A rectangle has a perimeter of 30 yards. If one side is 5 yards long, how long is the other side?
A. 15 yards
B. 25 yards
C. 10 yards
D. 30 yards

Answers

Answer:

C. 10

Step-by-step explanation:

5+5=10

10+10=20

10+20=30

Answer:

The other is 10 yards long

Step-by-step explanation:

For a given rectangle

Perimeter (P) = 30 yards

and one of rectangle is 5 yards

Now,

Perimeter of rectangle

P = 2l + 2b

30 = 2(5) + 2b

30 = 10 + 2b

30 - 10 = 2b

20 = 2b

b = 20 ÷ 2

b = 10 yards

Thus, The other is 10 yards long

2  3/4 hours

Step-by-step explanation:

We see from the figure that 2 students spent 1/4 hours and 3 students spent 3/4 hours.

So the total time spent is

2* (1/4) + 3(3/4) hours

= 1/2 + 9/4

=(2+9)/4  taking l.c.m
