Answer:
Step-by-step explanation:
Before giving the exterior angles, find the third angle. A triangle (all triangles) measure 180 degrees.
35 + 80 + x = 180
115 + x = 180
x = 180 - 115
x = 65
Exterior angles are supplements of the interior angles.
So the exterior angle to 65 degrees is 180 - 65 = 115
And the exterior angle to 35 degrees is 180-35 = 145
The exterior angle to 80 degrees is 180 - 100 = 80
Answer:
1.6
Step-by-step explanation:
Whenever you round to the nearest tenth, you'd have to check the hundredth position. If the hundredth digit is in the range of 0-4, the tenth position stays the same. If the hundredth digit is in the range of 5-9, you add one to the tenth. For example, if I had 2.36 and I wanted to round it to the nearest tenth, I see that the hundredth digit, or 6, is greater than 4, so it rounds up to 2.4. If I had 2.32 and I wanted to round it to the nearest tenth, I see that the hundredth digit, or 2, is less than 5, it rounds to 2.3.
The set of natural numbers is {1, 2, 3, 4, ...} basically positive whole numbers
The set of whole numbers is {0, 1, 2, 3, ...} which is the set of natural numbers with 0 included
The set of integers is {..., -3, -2, -1, 0, 1, 2, 3, ...} consisting of positive and negative whole numbers, plus zero as well
The set of rational numbers is the set of all fractions of the form a/b where b is not equal to zero. Any whole number, natural number, and integer is also a rational number.
If the number cannot be expressed as a rational number, then it is said to be irrational
------------------------------------------------------------------------
With all that in mind, the answers are "integer" and "rational" as you wrote in the comment section above. The value -25 is in the set {..., -3, -2, -1, 0, 1, 2, 3, ...} which is the set of integers. So we can say that -25 is an integer.
-25 is not a whole number based on the definition I wrote above. The set of whole numbers I wrote above does not include any negative values. This is why -25 is not a natural number either.
We can say that -25 is rational since -25 = -25/1 which is a fraction of integers. Since -25 is rational, it cannot be irrational.
Answer:
m<DBE =50°
m<ABD=150°
Step-by-step explanation:
Because of Straight Angles, All the angles will add up to 180 degrees
Let x be m<DBE
40+x+70+20=180
x+130=180
x=50
m<DBE will be 50 degrees
To find the m<ABD, we add m<FBA, m<FBE, m<DBE.
70+50+30=150
m<ABD = 150
