Answer:
x=26
Step-by-step explanation:
exterior angles theorem meaning they're equal to each other.
5x+7=8x-71
add 71 to 7
5x+78=8x
subtract 5x from 8x
78=3x
divide 78 and 3
x=26
to check your work plug 26 into each equation:
5(26)+7= 137°
8(26)-71= 137°
because they're the same you know that x must equal 26
hope this helps!❤
Answer:
5/2
Step-by-step explanation:
The scale factor for linear measures, such as perimeter, is the square root of the scale factor for areas. The ratio of larger area to smaller is ...
... 75/12 = 25/4
so the ratio of the larger perimeter to the smaller is ...
... √(25/4) = 5/2
Answer:
four more than a number
Step-by-step explanation:
For lines to be parallel, their slopes have to be the SAME.
x = -2 This is a vertical line (For the points on this line, x will always be -2, and y can be any number)
Since this is a vertical line, the parallel line has to also be vertical.
x = -5 (for the points on this line, x will always be -5, and y can be any #)
