Answer:
it is the equation which you have to solve.
Answer:
12) 5.96 ; 13)
Step-by-step explanation:
12). x and 5 are legs, so
opposite leg/adjacent leg = tangent 40°
5/x= tan40°, 5= x*tan40°, x= 5/tan40° ≈ 5.96
13). 15 is opposite leg
24 is hypotenuse
opposite leg/hypotenuse = sin(x)
sin(x) = 15/24
x = arcsin(15/24) ≈ 38.68°
Answer:
(6,6)
Step-by-step explanation:
The midpoint formula is 
. Substitute (2,10) and (10,2) into this formula and simplify.
30-25%=22.5
30-22.5=7.5
