Find the lengths and determine the measure of the missing angel (x)
inysia [295]
B= 60 
To find b you must do the pythagorean theorem because it is a right triangle
65^2 - 25^2=b^2
3600=b^2
60=b

x= 18 
To find x you must know that a triangle is made up of 180 degrees.
x= 180-(72+90)
x=180-162
x=18

hope this helped :)

How do i use the decimals 2.47,9.57,and 7.1 to write two different addition facts and two different subtraction facts?
VARVARA [1.3K]

<u>Answers</u>

2.47 + 7.1 = 9.57

7.1 + 2.47 = 9.57

9.57 - 2.47 = 7.1

9.57 - 7.1 = 2.47


<u>Explanation</u>

A fact family is a group of math facts using the same numbers.  In the case of addition/subtraction, you use three numbers and get four facts.

In this case we are going to write two different addition facts and two different subtraction facts as follows:

2.47,9.57,and 7.1

<em><u>Addition facts</u></em>

2.47 + 7.1 = 9.57

7.1 + 2.47 = 9.57

<em><u>Subtraction</u></em>

9.57 - 2.47 = 7.1

9.57 - 7.1 = 2.47
