Y+y+17+111+90=360
2y+128+90=360
2y=360-218
2y=142
y=142/2
y=71
thus, the angles are 71, 90, 111, 88.
Step-by-step explanation:
Input Equation can be rewritten:
= (9*1/2)+(7*-91/12)
= (9/2)+(7*-91/12)
= (4.5)+(7*-91/12)
= 4.5+(7*-91/12)
= 4.5+(-637/12)
= 4.5+(-53.083333333333)
= 4.5+-53.083333333333
= 4.5-53.083333333333
= -48.583333333333
hope this helps!
Answer:
B
Step-by-step explanation:
Reflection is a transformation that preserves lengths.
Triangle XYZ, with side lengths XY = 7 in, YZ = 5 in, XZ = 4 in, is reflected across the x-axis to result in △X'Y'Z'.
This means that corresponding sides have the same lengths:
- XY = X'Y' = 7 in;
- XZ = X'Z' = 4 in;
- YZ = Y'Z' = 5 in.
Find the perimeters of both triangles:
Hence, only option B is true.
Answer:
12
Step-by-step explanation:
you divide 36 by 3 and get z = 13
Answer:
about 1.4 hours
Step-by-step explanation:
3.13 gallons per minute.
60 minutes in an hour, so multiply both numbers by 60.
187.8 gallons per hour.
Divide the number of gallons we need to fill the tub the number of gallons put in per hour.
255÷187.8=1.375...
Round it, you get 1.4 hours.
It takes about 1.4 hours to fill the hot tub.
