There are two things you can do with angles. You can 1) set them equal to each other or 2) set their sum equal to a definite angle measure (like 180 or 90).
These angles are congruent. This is because they are opposite angles, and opposite angles are congruent. So in this case, we set these equal to each other.
1) Set up: x + 104 = 3x
2) Isolate x: 2x = 104
x = 52
I got x = 52, but it is always helpful to double check work. Hope this helps!
V - E + F = 2.....add E to both sides
V + F = 2 + E ...now subtract 2 from both sides
V + F - 2 = E <==
Answer:
x = 82°
Step-by-step explanation:
The triangle sum theorem states that the sum (total measure) of all angles in a triangle must add up to 180°.
Therefore:
60° + 38° + x° = 180°
98° + x° = 180°
98° – 98° + x° = 180° – 98°
x = 82°
Answer:
x=4 and y=1
Step-by-step explanation:
4x-y=15
2x+y=9
6x=24
x=24/6
x=4
4x-y=15
4(4)-y=15
16-y=15
-y=15-16
-y=-1 Divide both sides by -1
y=1
Answer:
She can get one 1/2 jug of orange juice
Step-by-step explanation:
1/2 = 4/8
7/8 - 4/8 = 3/8
3/8 is less than 1/2 so she can only get one 1/2.
