Answer:
The larger angle is 143
Step-by-step explanation:
x + y = 180 (This is the meaning of supplementary. Two angles make up 180 degrees)
4x - 5 = y
x + (4x - 5) = 180 Remove the brackets.
x + 4x - 5 = 180
5x - 5 = 180 Add 5 to both sides
5x - 5 +5 = 180 + 5 Combine
5x = 185 Divide by 5
5x/5=185/5
x = 37
y = 4*37 - 5
y = 148 - 5
y = 143
Answer:
△E'L'M'
Step-by-step explanation:
-90° rotation = 270° rotation
Which maps (x,y) onto (y,-x)
L' (2,-3)
M' (7,-6)
E' (-3,-7)
Answer:
1,757,600
Step-by-step explanation:
26x26x26x10x10 = 1,757,600
You have to make the denominators(bottom of the fraction) the same in order to combine the fractions.
To make the denominator of
the same as
, you multiply the top and bottom of the fraction by 2 (because they both have a common multiple of 4)

So:

Answer:
50º
Step-by-step explanation:
Angle D & B are vertical angles, meaning they are equal in measure.
So if Angle B = 50º, then Angle D must also be 50º.
Hope this helps! Have a great day!
