Step-by-step explanation:
Number A
= 6√2 - 5√2
= (6 - 5)√2
= √2
Number B
= √11 + 3√11
= (1 + 3)√11
= 4√11
Answer:
(i)
<u>Given</u>
<u>Also we see that</u>
- ∠ABC = ∠DBE as refer to same angle
<u>Since two angles of triangles are congruent, the triangles are similar by </u><u>AA similarity postulate</u>
(ii)
<u>In similar figures corresponding parts have same ratio. Use ratios to find the value of x:</u>
- AB/EB = AC/ED
- 12/8 = x / 4
- x = 4*12/8
- x = 6 cm
I’m pretty sure the correct answer is C 42
Answer:
The power developed by the 1st crane is twice the power developed by the 2nd crane.
Step-by-step explanation:
According to the question,
work done by both of the cranes are the same. Let it be W.
Then power developed by the first crane,
=
unit -----------------(1)
and, the power developed by the 2nd crane,
=
unit ------------------(2)
So, we get that,

So, the power developed by the 1st crane is twice the power developed by the 2nd crane.
