Answer 1

@CallMeKiki @sugarplum15

Answer 2

is that a right angled triangle ?

Answer 3

No. It doesn't have the box in the corner

Answer 4

its mentioned that its a right angled triangle

Answer 5

use pythagoras

Answer 6

have you been able to do ?

Answer 7

So a^2 would be 8.

Answer 8

And 20 would be c^2?

Answer 9

\[a ^{2} = b ^{2} + c ^{2}\]

replace a by 20, b by x and c by 8

\[(20)^{2} = (x)^{2} + (8)^{2}\]

Answer 10

@OM14forever better now ?

Answer 11

how do I find x

Answer 12

20/8=

Answer 13

is that what I should do

Answer 14

\[x ^{2} = 20^{2} - 8^{2}\]

Answer 15

so 12

Answer 16

\[x ^{2}= 400 - 64\]
\[x ^{2} = 336\]
\[x = \sqrt{336} = 18.3\]

Answer 17

nearest to tenth will be x= 18

Answer 18

ok thanks
