Answer:
5
Step-by-step explanation:
by pythagoras theorem
(hyp)^2=(leg1)^2+(leg2)^2
the hypotenuse is the side opposite to 90 degree (BC=13)
AC=leg 1 = 12
13^2=12^2 + leg 2^2
169=144+ leg 2^2
leg2 ^2=169-144
leg2^2= 25
leg2= root 25
leg2=5
Answer:
− 19x + 12
Step-by-step explanation:
That expression is equivalent to 1/2(6-16) because since you are distributing 1/2 you are going to divide 6 and -16 by 1/2 and that will give you 3x-8
7 -3 2/5
= 7 -17/5
= 35/5 -17/5 (common denominator is 5)
= 18/5
= 3 3/5
The final answer is 3 3/5~
