Given

The three sides are given 24, 30 and 18.

Explanation

To find the triangle is acute, obtuse or right triangle.

To determine whether the triangle is acute, right, or obtuse.add the squares of the two smaller sides, and compare the sum to the square of the largest side. Since this sum is greater, the triangle is acute.

A

If the sum of the squares of the two smaller sides is equal to the square of the largest side , then it is right triangle.

Now c.

\begin{gathered} 30^2=24^2+18^2 \\ 900=576+324 \\ 900=900 \end{gathered}

Answer

Hence the sum of the squares of the two smaller sides is equal to the square of the largest side , then it is right triangle.

The correct option is A.

What is this number in standard form?
Andrej [43]

Answer:

500.61

Step-by-step explanation:

5 multiplied by 100 = 500

1/10 = 0.1, So 6 multiplied by 0.1 = 0.6

1/100 = 0.01, So 1 multiplied by 1 = 0.01

500 + 0.6 + 0.01 = 500.61

mestny [16]

The expressions of the number of radians can be expressed in the ways below.

<h3>How to write the expressions</h3>

The radius = 1.9 km

The angular speed = 3.1 radians per hour

a. The expression of t from the number of radians

θ = π/2 + 3.1t

<h3>b. Expression from the East</h3>

x = rcosθ

= 1.9cos(π/2 + 3.1t)km

<h3>c. Expression from the north of the center</h3>

= rsinθ

= 1.9sin((π/2 + 3.1t)km
