Answer:?
Step-by-step explanation:
Answer:
y = 140, x = 159
Step-by-step explanation:
Angle y:
we can find this angle by subtracting 40 from 180, 180-40 = 140 = y
Angle x:
Some measure of an angle plus angle b is equal to 180 degrees: 180-61 = 119
We can now find the measure of the third angle of the triangle: 180-(119+40) = 21
The third angle plus angle x is equal to 180: 180-21 = 159 = x
5 questions each 4 choices guess 3 out of 5 correctly?
5*4=20 20/3=6.67 , My guess is that the outcome of you probably getting 3 / 5 correct is a 79.9 percent chance.
13-3/2 you need to make a common denominator, so
26/2-3/2 then subtract the numerators, the denominator remains.
23/2 now simplify the fraction
11½ this is because 22/2+1/2=23/2, and 22/2=11, so 11+1/2 or 11½
