Answer:
b) 105°
d) 130°
Step-by-step explanation:
An external angle has the same measure as the sum of the remote internal angles.
b) ? = 25° +80° = 105°
d) ? = 35° +95° = 130°
_____
This should be fairly obvious if you consider that the adjacent internal angle together with the external angle totals 180°, and the adjacent internal angle together with the other two internal angles totals 180°.
If the two "remote" angles are A and B, and the adjacent internal angle is C, then we have in symbols ...
A + B + C = 180° = ? + C
If we subtract C, then we find ...
A + B = ? . . . . . . the fact we used above
Answer:
2*t
Step-by-step explanation:
That should be it...
Just multiply 2 by t
Answer:
45!
Step-by-step explanation:
Solve for y and then graph it on a graphing calculator or since it doesn’t have a exponent you know it’s just a line because it would be the like y=4 which is a horizontal line at 4
Area of a parallelogram = bh
First, find b (base):
b = 12
Then find h (height):
h = 10
Multiply:
120
The answer is D) 120 units^2
