Answer:
65°
Step-by-step explanation:
If you add all the angles in a triangle, they equal 180°. You can subtract given angles to find missing angles.
Let's first subtract 25° from 180°. 180° - 25° = 155°.
This is a right triangle, so we know there is also a 90° angle. Also subtract this. 155° - 90° = 65°.
We are left with 65°. This is the measure of the third angle.
The triangle's angles are, 25° ; 90° ; 65°
Answer:
-0.64
Step-by-step explanation:
Given:
4[2/5(-2.5)]
Find:
Value
Computation:
⇒ 4[2/5(-2.5)]
⇒ 8 / [-12.5]
⇒ -0.64
Answer:
2
Step-by-step explanation:
The slope of the line is 2. The slope is rise over run, or change in y over change in x. So to find the slope count how much each value changes, in this graph y changes +2 and x changes +1. So the slope is 2/1 or just 2. One way to visually check the slope is to remember fraction slopes will make the line flatter and other whole numbers make the line steeper.
Answer:
From these examples, we can conclude, we will get a whole number when we divide if the numerator of the fraction is a factor of the whole number
Step-by-step explanation:
Lets look at a couple of examples
Example 1
4 ÷ 1/3
Copy dot flip
4 * 3/1 = 12
Whole number
Example 2
2 ÷11/12
Copy dot flip
2 * 12/11
24/11
11 goes into 24 2 times
11*2 = 22
24-22 =2
11 goes into 24 2 times with 2 left over, The left over goes over the denominator.
2 2/11
2 2/11 is a mixed number not a whole number
Example 3
8 ÷2/11
Copy dot flip
8 * 11/2
88/2
44
From these examples, we can conclude, we will get a whole number when we divide if the numerator of the fraction is a factor of the whole number
