How do i go about solving this question? i need major .

Assuming that this triangle is a right-angled triangle (this question does not state this crucial fact meaning that this question can not be answered) we can use Pythagorus theorem to solve this.

a squared plus b squared = c squared

15 squared plus 8 squared = x squared

225 plus 64 = x squared

289 = x squared

The square root of 289 is equal to 17

Therefore x = 17

.

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
