Step-by-step explanation:
1/4(0.25)
1/2 + 1/4 = 3/4 (0.75)
Answer:
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
We can notice that the balance beam has in one side 7 balls and in the other one 5 balls and a square
The balance beam is balenced
Let x be the square mass
- x+5 = 7 substract five from each side
- x+5-5 = 7-5
- x = 2
The solution is 2
C fits perfectly what we prooved
Side ST is congruent to TU, so the angles opposite those lines are also congruent (angles S and U)...so both would be 54. S=54 and U=54...since all 3 angles in a triangle add up to 180 degrees, angle T=72 (180-54-54=72)
Answer:
∠AEC measures 90°
Step-by-step explanation:
Angle AED is a "straight angle", so angles AEC and CED are a linear pair. The angles of a linear pair are supplementary, so angle AEC is supplementary to right angle CED:
∠AEC = 180° -∠CED = 180° -90°
∠AEC = 90°
