A number y is rounded to 2 decimal places
Yakvenalex [24]
Y can be rounded up to 1.51 from a minimum value of 1.505
This is the lower bound.

y can be rounded down to 1.51 from a maximum value of 1.515
this is the upper bound.

y is between the lower bound and the upper bound so y is between 1.505 and 1.515

This is shown as 1.595<=y<1.515

<= is the typed out version of (greater than/equal to) which is < with a line under it.

Assume: Triangle CDE is a right triangle and Angle D is a right angle. What is the length of the missing side? A) 26 . B) 25 . C
kramer

Answer:

Length of base DE = 24 units

Step-by-step explanation:

Given:

In given triangle, right angle at D

SO,

Perpendicular of given triangle = 32 unit

Hypotenuse of given triangle = 40 unit

Find:

Length of base DE

Computation:

Using Pythagoras theorem

Base = √Hypotenuse² - Perpendicular²

Length of base DE = √Hypotenuse of given triangle² - Perpendicular of given triangle²

Length of base DE = √40² - 32²

Length of base DE = √1,600 - 1,024

Length of base DE = √576

Length of base DE = 24 units
