The last one is the answer
The sum of 2 complementary angles equals 90 degrees.
If angle 1 and 2 are complementary and angle 1 and 3 are also complementary than angle 2 would have to be the same as angle 3.
The answer would be true.
If we have the equation of a line: y=ax+b
How to find a if with only the x<span>-intercepts (called m)</span> and y-intercepts (called n)
+ First we have y=0 and x=m or 0=a*m+b or b= -a*m
+ Then we have x=0, y=n or n=a*0+b or b=n
And if m≠0 we have a= -n/m
and if m=0 this line has no slope
5x^2= 2205
Divide both sides by 5
x^2=441
Find the square root of both sides
x= 21
Answer:
? What M? What is impossible?
