frame is 10 feet by 5 feet. How long, to the nearest tenth of a foot, must
the cross wire across the diagonal be?

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

i am not sure :

step-by-step explanation:

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)

your correct answer is c. he organized a political resistance group based on islam.

im sorry for the poor quality answer.
