Can I get some help on these and explain if you can im confused

For the first one the answer is 5.8

Step-by-step explanation:

Because you are using Pythagoras

you need to half 6 to get 3, as the its a right angle triangle

so for Pythagoras you do 3^2+5^2=34

root 34=5.8!

for all those questions you use Pythagoras!

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high
