Estimate √125 to the nearest integer.

Damm [24]

Given:

The number is $\sqrt{125}$ .

To find:

The estimate value of given number.

Solution:

We have,

$\sqrt{125}=\sqrt{5\times 5\times 5}$

It can be written as

$\sqrt{125}=5\sqrt{5}$

We know that, $\sqrt{5}\approx 2.236$ . So,

$\sqrt{125}=5(2.236)$

$\sqrt{125}=11.18$

Approx the value to the nearest integer.

$\sqrt{125}\approx 11$

Therefore, the required integer is 11.

A certain triangle, one angle measures ten degrees more than the second angle and ten degrees less than the third angle. What is

zheka24 [161]

Answer:

50°

Step-by-step explanation:

Let :

Let the angle = x

Second angle = x + 10

Third angle = x - 10

Sum of angles in a triangle = 180

x + (x + 10) + (x - 10) = 180

x + x + 10 + x - 10 = 180

3x = 180

x = 180 / 3

x = 60

Smallest angle :

x - 10 = 60 - 10 = 50°

Zx and Zy are supplementary angles. Zy measures<br> 156°<br> What is the measure of Zx?

cupoosta [38]

Answer:

Zx = 24 degrees

Step-by-step explanation:

since it is supplementary it adds up to 180 degrees. so you have part of the angle (156 degrees) so the equation would be 180 - 156 = Zx (origionally Zx + 156 = 180).
