1.x=-8
2.x=-2
3.x=1.6
4.r=-36
5.n=- 153/5
Answer: 71 degrees.
Step-by-step explanation:
Due to the triangle being isosceles (Two sides are equal), we can assume that the angles will also be equal.
You can take 180 (The total of a triangle) and subtract by the known degree
180 - 38 = 142
Now we divide 142 by two, ONLY because this is case; both angles will be the same degree.
142 / 2 = 71
Therefore; x = 71
Answer:
Step-by-step explanation:
Both numbers are integers (not fractions)
if you write an integer in scientific notation:
1) inset a comma between first and second digit (3.70000000)
2) calculate all digits on the right side of insetting comma (there are 8 digits after a comma: 7,0,0,0,0,0,0,0)
3) a fraction from point 1) you multiply by 10 to the power, which is equal to a number of digits after comma (8)
4) according this tips, you have 
5) for a better notation, you may remove ending zeros
Answer:
A1(8,0)
B1(12,6)
C1(6,8)
Step-by-step explanation:
If its dilated by a scale factor of 1/2, that means for each x and y-coordinate you divide by 2 to get the new scale factor
Originally A(16,0) so now it would be A1(8,0)
Originally B(24, 12) so now it would be B1(12,6)
Originally C(12, 16) so now it would be C1(6,8)
In a number line which goes from north to south, the upper portion has positive numbers and the lower portion has negative numbers.
so the elevation at Mt. McKinley will be written as +20,236
and at death valley it will be -282
