PLEASE I need help on these 4 problems you don’t have to do them all but if you can at least do one of them TYSM

Answer:

For right angle triangle,

we use Pythagoras theorem that is:

$c^{2} =a^{2} +b^{2}$

c = $\sqrt{a^{2} +b^{2} }$

For question 1:

c = ?

a = 40

b = 9

putting them in formula,

c = $\sqrt{40^{2} + 9^{2} }$

c = 41

For question 2:

c = ?

a = 12

b = 13

putting them in formula,

c = $\sqrt{12^{2} + 13^{2} }$

c = approximately 17.69181

For question 3:

c = 35

a = 20

b = ?

putting them in formula,

$c^{2} =a^{2} +b^{2}$

$35^{2} = 20^{2} + b^{2}$

1225 = 400 + $b^{2}$

$b^{2}$ = 1225 - 400

$b^{2}$ = 825

$\sqrt{b^{2} } = \sqrt{825}$

b = 5 $\sqrt{33}$

For question 4:

c = 37

a = 20

b = ?

putting them in formula,

$c^{2} =a^{2} +b^{2}$

$37^{2} = 20^{2} + b^{2}$

1369 = 400 + $b^{2}$

$b^{2}$ = 1369 - 400

$b^{2}$ = 969

Taking square root on both sides

b = 31.12

Hope it helps.

Probability!

Reil [10]

Answer:

26/31

Step-by-step explanation:

N(B)=12

N(G)=14

N(Y)=5

N(S)=N(B)+N(G)+N(Y)

=12+14+5

=31

Now,

P(Not getting yellow)=N(B)+N(G)/N(S)

=12+14/31

=26/31

When a point lie on the x-axis what do you know about its y coordinate? When a point lies on the y-axis,what do you know about i

Sergeeva-Olga [200]

When the point is on the x axis, then the y coordinate=0
when the pointis on the y axis then the x coordinate=0 as well
