Y=12
x=6
The triangle is a 30-60-90 triangle!
1. x=5
Explanation:
2(2x-3)=x+9
4x-6=x+9
-x -x
3x=15
x=5
2. x=-9
Explanation:
2(x+19)=x+29
2x+38=x+29
-2x -2x
9=-x
-9=x
Answer:
z=40 degrees
x=90 degrees
y=40 degrees
Step-by-step explanation:
To solve z you know that 50+90+z= 180 degrees. So z equals 40. To solve x you subtract 90 from 180 to get 90 degrees. To solve you add 50+x+y. You know that x= 90. You would add the angles together to get 180 degrees. 50+90=140 and 180-140 equals 40. Sorry if i'm wrong.
Answer:
The bank charged 56 dollars in interest
Change in temperature = 12 - (-13) = 12 + 13 = 25
Number of hours = 25/5 = 5 hours.
Required time = 4 am + 5 hours = 9.am
