Answer:
Use the "find vertically opposite angle" method.
a = 80°
To find the other angles:
Since the angles equal up to 360 which makes a full circle shape...
360 - 80 - 80 = 200 (B and C)
200 ÷ 2 = 100 (Angle for B and C since they are vertically opposite, hence having the same angle)
b = 100°
c = 100°
Answer:
Hence, the value of y is undefined.
Step-by-step explanation
from the property, log_a (b) = (log(a))/log(b).
The value log (-7) was not defined. So, the entire log value also not defined.
Hence, the value of y is undefined.
Answer:
6 square units
Step-by-step explanation:
Given shape is of a trapezoid:
Area of shape = area of square + area of triangle
Answer:
35 is the 'is' and 40 is the 'of'
Step-by-step explanation:
is/of = %/100
35/40 = x/100
cross-multiply to get:
40x = 3500
x = 3500/40
x = 87.5
the answer is C, I think because parallel lines never touch
