This is a same side interior angle, which means that the two angles, when added, will equal 180°
y + 72 = 180
Isolate the y, subtract 72 from both sides
y + 72 (-72) = 180 (-72)
y = 180 - 72
y = 108
A) 108°, is your answer
hope this helps
Answer:
1.
T mBAC = mB'A'C'
F 2mABC = mA'B'C'
F BC = 2B'C'
T 2XA = XA'
2
D'(-2/3; -1)
E'(-1;1)
F'(1;1)
G'(1;-1)
3
the centre is L(0;-2)
the scale factor is 4
length J'K' = 4JK
the measure of L is equal the measure of L'

Answer:
y=-x-2
Step-by-step explanation:
The slope is negative 1 and the y intercept is -2
Answer:
Shania has read the most pages.
Step-by-step explanation:
Following the formula y = mx + b.
Kevin already read 45 pages.
y = mx + 45
He reads 20 pages per hour, since it has per hour, we put it has "m"
y = 20x + 45
Shania already read 5 pages
y = mx + 5
Shania reads 25 pages per hour
y = 25x + 5
We need to find out how many pages they read after 20 hours, plug 20 into x.
Kevin
20(20) + 45 =
400 + 45 =
445
Shania
25(20) + 5 =
500 + 5 =
505
Shania read 60 more pages than Kevin.
Sum of the interior angles of any triangle equal 180° ;
So :
90° + 24° + T = 180°
114° + T = 180°
subtract both sides 114
T = 180° - 114°
T = 66°
