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 median is 6.5
Step-by-step explanation:
To find the median, first organize the numbers from least to greatest:
1, 4, 6, 6, 7, 8, 9, 10
The median is always the number in the middle, but since there are eight numbers here, there will be two numbers in the middle: 6 and 7.
To solve for this, we have to find the average of the numbers.
Add the two numbers together and then divide by 2 (we divide by 2 because we are averaging two numbers).
(6 + 7)/2
13/2
6.5
Answer:
62.4
Step-by-step explanation:
1. 1.3x+37.44=1.9x
2. 1.3x+37.44-1.3x=1.9x-1.3x
0.6x=37.44
3. x=37.44/0.6=62.4

Answer:
s = -18
b is correct option
Step-by-step explanation:

By cross multiplication
4×9 = -2×s
0r
-2×s = 4×9
s = 36 ÷ -2
s = -18
