Which number has a 6 that is 1/10 the value of the 6 in 527.6?
Furkat [3]

The number that has a 6 that is 1/10 the value of the 6 in 527.6 is B. 982.46.

<h3>How to illustrate the information?</h3>

It should be noted that we are to simply find the place value of the numbers.

In 527.6, the place value is 1/10.

On the other hand, in 982.46, the place value is 1/100.

Therefore, the number that has a 6 that is 1/10 the value of the 6 in 527.6 is 982.46.

The angles in a triangle are in the ratio 2:3:4. Find the size of the smallest angle.
mars1129 [50]
Angles in a triangle add up to 180
2:3:4...added = 9

2/9 (180) = 360/9 = 40 <=== smallest angle
3/9 (180) = 540/9 = 60
4/9 (180) = 720/9 = 80

Solve the following problems using Pythagoras. Include a diagram . a. How long must a ladder be to reach 12 ft up the wall, if t
RUDIKE [14]

The length of ladder used is 12.25 ft.

<h3>What is Pythagoras theorem?</h3>

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse .

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

example:

The hypotenuse of a right-angled triangle is 16 units and one of the sides of the triangle is 8 units. Find the measure of the third side using the Pythagoras theorem formula.

Solution:

Given : Hypotenuse = 16 units

Let us consider the given side of a triangle as the perpendicular height = 8 units

On substituting the given dimensions to the Pythagoras theorem formula

Hypotenuse^2 = Base^2 + Height^2

16^2 = B^2 + 8^2

B^2 = 256 - 64

B = √192 = 13.856 units

Therefore, the measure of the third side of a triangle is 13.856 units.

given:

base=  2.5 ft,  

perpendicular= 12 ft

Using Pythagoras theorem,

H² =  B² + P²

H² = 2.5² + 12²

H² = 6.25+ 144

H= 12.25 ft
