Step-by-step explanation:

28squared+34squared=2809 find the square root and it equals 53

4.5squared+6squared=56.25, square root equals 7.5

How to solve X + y = 2<br> X - y = 4
SpyIntel [72]
So y+x=2
x-y=4
one way is subsituteion where yousubisutte one of the number for another exg

x-y=4
add y to both sides
x=y+4
subsitute y+4 for x in x+y=2
 y+4+y=2
2y+4=2
subtract 4 from both sides
2y=-2
divide both sides by 2
y=-1
subsiutte
x+y=2
x-1=2
x=3




or elimination

x+y=2
x-y=4
add the two equations and cancel the y terms

x+x+y-y=2+4
2x=6
divide both sides by 2
x==3
subsitute
x+y=2
3+y=2
y=-1


so x=3
y=-1

For an Isosceles triangle of base b and congruent sides, x units long, what is the range of angle measures for the angle measure
olga2289 [7]

Answer:

the desired range is 0° < angle < 180°

Step-by-step explanation:

If 2x were just slightly less than b, then the angle opposite the base would be just less than 180 degrees.

The larger the value of x, the further the intersection of the two congruent sides is moved away from the base b.  The angle between these two congruent sides would approach but never equal zero.

Thus, the desired range is 0° < angle < 180°
