Step-by-step explanation:
<1 = 90 - 32
= 58
bd is a traversal to parallel line ab and dc
<1 = <bdc ( alternate angles) = 58
in right triangle edc
90 - 58 = <3 = 32
<2 = 58

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
------------------------------------------------------------------
I think the answer is no. Not all right angles are similar. For them to be similar, one triangle should be an enlargement of the other triangle. The dimensions of the triangles should have a constant ratio for the two shapes. This is not true for all right triangles.
