Answer:
x = 55°
Step-by-step explanation:
120° = x° + 65° (alternate interior angles are congruent)
Subtract 65 from each side
120° - 65° = x° + 65° - 65°
55° = x
Therefore,
x = 55°

Push Mower
------------------------------------------------------------------
It takes 5 hours to complete the job
1 hour = 1/5 of the job
------------------------------------------------------------------
Riding Lawn Mower
------------------------------------------------------------------
It takes 3 hours to complete the job
1 hour = 1/3 of the job
------------------------------------------------------------------
Push Mower + Riding Lawn Mower
------------------------------------------------------------------
1 hour = 1/5 + 1/3
1 hour = 3/15 + 5/15
1 hour = 8/15 of the job.
------------------------------------------------------------------
Calculate time needed to complete
------------------------------------------------------------------
8/15 of the job takes 1 hour
8/15 of the job = 1 hour
------------------------------------------------------------------
Divide by 8/15 on both side
------------------------------------------------------------------
8/15 ÷ 8/15 of the job = 1 ÷ 8/15 hour
Whole of the job = 1 x 15/8 hours
Whole of the job = 15/8 hours
Whole of the job = 1 7/8 hours
------------------------------------------------------------------
Answer: 1 7/8 hours

Answer:
Length of the enlarged cube is 10 cm.
Step-by-step explanation:
We are given that,
Length of the cube = 5 cm.
The cube is enlarged by a scale factor of 2.
Since, enlargement increases the size of the figure.
So, the length of the cube will increase by a factor of 2.
That is,
Length of the enlarged cube = 5 × 2 = 10 cm
Hence, the length of the enlarged cube is 10 cm.
