Answer:

length of diagonal d is 50 m. (first option is correct)

Step-by-step explanation:

using pythagoras theorem

here 40 and 30 are the legs of the triangle so let them be a and b respctively.

And d is the hypotenuse so let it be c

a^2 + b^2 = c^2

40^2 + 30 ^2 = d^2

1600 + 900 = d^2

2500 = d^2

\sqrt{2500} = d

50 = d

Triangle LMN similar to triangle OPQ find the measure of side PQ round your answer to the nearest 10th if necessary
sergejj [24]

*see attachement for the triangles given

Answer:

PQ = 6.8

Step-by-step explanation:

Corresponding sides of similar shapes or figures are proportional to each other. Since ∆LMN ~ ∆OPQ, the ratio of their corresponding sides would therefore be equal. Thus:

LN/OQ = MN/PQ

LN = 5

OQ = 17

MN = 2

PQ = ?

Plug in the values

5/17 = 2/PQ

Cross multiply

5*PQ = 2*17

5*PQ = 34

PQ = 34/5

PQ = 6.8
