Answer:b
Step-by-step explanation:
Answer:
y=90 degrees
x=51 degrees
Step-by-step explanation:
all right angles are 90 degrees
90+39=129
180-129=51
Answer: x = 10
Explanation: The bottom left angle is 90 degrees because of the symbol. ( Make sure you know this for future problems.) The whole triangle needs to add up to 180. This isn’t the right way to solve this kind of problem but I know how to solve it using this way and I know the at 10 is the right answer. The other two angles need to add up to 90 because 90 + 90 = 180. So basically I just substituted the same number into x until I added both outcomes and got 90. I hope you understand that cause I don’t really know how to explain it well. Let me try and show you.
3(x)+5 6(x)-5
Now you have to plug in the same number for x until both numbers add to ninety.
3(5)+5 6(5)-5.
( 5 isn’t the right number for x this is just an example. )
You end up with 20 for the first one, and 25 for the second one. 20 + 25 = 45 and 90 + 45 is only 135. So this means that 5 isn’t the right answer and you need to substitute a higher number in for x.
3(10)+5 6(10)-5
( This is the right setup. )
You end up with 35 for the first one and 55 for the second one after you distribute and solve. Now you have 35 and 55. 35 + 55 = 90 and 90 + 90 = 180. This is how you know that you are right. I hope this helps. :)
There are 10 shaded tiles. 30% of that is 3 There are 30 total tiles. 3/30=.10 or 10%. The fraction is 3/30. 3/30 needs to be simplified. 3/3=1 and 30/3 equals 10. 1/10 is the simplified version of the fraction and the answer
Area= Length x Width
A= 3x8
A(x) = 3
A(8) = 3
You solve
