ABC is a right triangle right-angled at B.
AC is the hypotenuse, length 96cm
Angle C=30 degrees, therefore AB is the short leg opposite angle C.
sin(30)=opp/hyp=AB/AC=AB/96
=>
AB=96sin(30)=96(1/2)=48 cm.
The error made was in step two because you do not add 1 and 48, you subtract. this would result in "no solution" since you can't find the square root of a negative number
Answer:
13cm
Step-by-step explanation:
Let the given lengths be the opposte amd adjacent sides of a right triangle'
The missing side will be the hypotenuse
Using the pythagoras theorem;
hyp^2 = 5² + 12²
hyp² = 25 + 144
hyp² = 169
hyp =√169
hyp = 13cm
Hence the missing one is 13cm
