OpenStudy (anonymous):

Area= 42.25 x= 6.5

jimthompson5910 (jim_thompson5910):

The area isn't 42.25

jimthompson5910 (jim_thompson5910):

if it helps, you can rotate the triangle so that the side length of 5 is the base (making 12 the height) |dw:1412380242371:dw|

OpenStudy (anonymous):

Okay, so the area is 30. Is x right? @jim_thompson5910

jimthompson5910 (jim_thompson5910):

correct

jimthompson5910 (jim_thompson5910):

how can you use this to find x?

OpenStudy (anonymous):

I am unsure. Could you help me?

jimthompson5910 (jim_thompson5910):

refer back to the original triangle |dw:1412381557041:dw|

jimthompson5910 (jim_thompson5910):

what is the base? what is the height?

OpenStudy (anonymous):

The base is 5 and the height is 12.

jimthompson5910 (jim_thompson5910):

no focus on this orientation |dw:1412381616416:dw|

jimthompson5910 (jim_thompson5910):

13 runs along the ground (once again)

OpenStudy (anonymous):

so 13 is the base, and x is the height?

jimthompson5910 (jim_thompson5910):

yes
