Answer:
x = 80, y = 122
Step-by-step explanation:
I got this equation by using vertical angles to create a complimentary angle pair (they sum to 90 degrees).
3/4x+2/5x-2=90°,
23/20x - 2=90°,
23/20x = 92°,
92/(23/20)
20/(1/4)
20(4)
= 80.
Since the angles are a linear pair on the left side(they sum to 180 degrees). Just subtract 180 from 3/4x-2 and substitute x into the expression.
180-(3/4(x)-2), 180-3/4(80)+2 = 120+2 = 122
It would be B because eaxh section either repeats itself or is close to repeating its previous part
Answer:
9/10 I do this a lot
step-by-step explanation:
1/2 changes to 5/10 and 2/5 becomes 4/10 then you add and there is your answer
I got 65/153 since you actually multiply by the reciprocal of the second fraction.
3, 15, 75, 375, and here's why:
Basically, it's asking you to take 3, and multiply it by five each time to get a pattern.
1: 3
2: 3*5 = 15
3: 15*5 = 75
4: 75*5 = 375
Add these together:
3 + 15 + 75 + 375 = 468
Your answer is "A)", 468.
