Answer:
<d = 25 degrees and <e = 130 degrees
Step-by-step explanation:
We have a vertical angle, so the opposite sides of this angle are the same. This means that the angle opposite to 25 degrees also measures 25 degrees. We have one angle of the triangle. Since the triangle is isosceles, the angle d is the same as 25 degrees.
<d = 25 degrees
The interior angles of a triangle add up to 180 degrees, and we now have 2 angles, so:
<e = 180 - 25 - d
<e = 155-25
<e = 130 degrees
Answer:
The other number is 14.
Step-by-step explanation:
To find the other number, all you have to do is divide 1/7 by 2.
Hope this helped!
First you must find out the pattern
The pattern is 3+3 = 6 minus one equals 5+5 = 10 minus one equals 9+9 = 18 minus one equals 17+17
The next two would be 17+17 = 34. 34 minus one equals 33
The next two answers are 34 and 33
Answer:
95
Step-by-step explanation:
Being a sum of two elements that include units and tens, we can make the sums of the units first, and then add the tens together.
So, if we have 45+50, we can first separate the units: 5 + 0 =5
Then, we separate the tens: 4+5=9
Now, we only join the sums of the units and tens, and that will be the end result. 95
21²=21×21
21×21=441
2,870+441=3,221
