Is there any way any of you could help him please? I don't have time at the moment. Thank you so much in advance!

Answer 2

formula to find area of right triangle is \[\large \rm A=\frac{1}{2} b*h\] where b is base
and h is height

Answer 3

and it's a right triangle so to find missing side you can use Pythagorean theorem
a^2+b^2=c^2
where c is the longest side of right triangle (hypotenuse )

Answer 4

25

Answer 5

is A^2 + B^2= C^2

Answer 6

what's 25 ??

Answer 7

5

Answer 8

correct that's the 3rd side now just use the formula to find area of right triangle

Answer 9

30

Answer 10

is that the answer

Answer 11

how did you get that ?

Answer 12

0.5*5*12

Answer 13

1/2*5*12

Answer 14

then yes that's correct

Answer 15

thanks

Answer 16

remember it should be in `square ` units and np :=))

Answer 18

You need the formula for distance between two points \((x_1,y_1)\) and \((x_2,y_2)\):
\[d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}\]

You know one of the points, and you can find the other by counting marks on the graph from the origin. Doesn't matter which point you call \((x_1,y_1)\) and which point you call \((x_2,y_2)\).

This is just the Pythagorean theorem in disguise...the hypotenuse is the distance.
