First, since AB and CD are parallel, you can find the value of C, which is a consecutive interior angle of A.
180-78=102
So, angle C is equal to 102°
Second, you can subtract 115 and 102 from 360 to find angle DCE.
360-115-102=143.
Third, add 32 to 143 to see if they add up to 180.
32+143=175
Since CD and EF are not connected by a 180° angle, they are not parallel.
I hope this is correct!
Answer:
7/8
Step-by-step explanation:
since the denominators are the same, you simply just add the numerators.
Answer:
option 4 is the right answer
Answer:
70
Step-by-step explanation:
First you want to find the amount of x per 1 y so you divide 21 by 3 to get when x = 7 y = 1. Now you can just multiply 10 by 7 to get 70.
I hope this helps!
E=mc^2 is <em>not </em>a mathematical formula. E=mc^2 is used in various sciences relating to energy.
E = energy
m = mass
c = constant (speed of light)
