Explanation

The triangle with sides 26 cm, 24 cm and 10 cm is right angled, where the hypotenuse is 26 cm.

Area of the triangle =1/2 x base x height => 1/2 x 24 x 10 = 120 sq.cm

Explanation

• A pyramid is a polyhedron with a square base and four triangular faces that meet at the apex.
• The base of a pyramid is always a square, which provides a stable foundation for the structure.

Explanation

The unit cell with the highest symmetry is cubic. 

Among all crystal systems, the cubic unit cell has the highest symmetry because:

• All sides are equal: $a=b=c$

• All angles are right angles α=β=γ=90∘

• It has multiple axes of symmetry and mirror planes

This high degree of symmetry leads to highly uniform and isotropic properties.

Explanation

An angle with a measurement of less than 90° is called an acute angle.

L shape forms 90° so if the arms of an angle open up less than an “L”, an acute angle is formed.

Explanation

Given :

The expression log 15 + log 7

To find :

To express in a single logarithm form

Formula :

log a + log b = log ab

Solution :

Write down the given expression

The given expression is

log 15 + log 7                  

Express in a single logarithm form

Use the formula log a + log b = log ab

Thus we get

log 15 + log 7

= log ( 15 × 7 )

Explanation

• The degree of a polynomial is the highest power of the variable (x) in the polynomial.
• In this case, the highest power is 5, so the degree is 5.
  

Explanation

To find the size of the largest square slabs, we need to find the greatest common divisor (GCD) of the length and breadth of the room.

First, let's convert the length and breadth to centimeters:

Length = 5 meters 44 cm = 544 cm

Breadth = 3 meters 74 cm = 374 cm

Now, we find the GCD of 544 and 374:

GCD(544, 374) = 34

So, the size of the largest square slabs that can be paved on the floor is 34 cm x 34 cm.

Explanation

When cosθ = 90°, the value of cosθ is zero and so the work done is always zero.
