In ΔABC, m∠ACB = 90°, and m∠ACD = 45°. Find:AC, if CD =6√2 in.

can u put answer and solution

actually because we know its a 45 45 90 triangle, its an isosceles triangle so we can use base angle's theorem to figure out that AD=CD=6√2

then we can use the Pythagorean theorem to find that 6√2^2+6√2^2=12

Since CD and AC are both 6 x Square root of 2, AC would 12 because 6 Times Square root of 2 all to the power of 2 is 36 x2, which is 72, and 72 for both sides adds up to 144. Then you can find the square root of 144, so AC=12

ac=12

answer is 12

Im a monkey and i know it is 12 cmon yall the answer is 12

100% sure the answer isn't 6. Though I am struggling with this also, how do you find the sides when you only know the altitude?

Its 12

Yes its 12

thanks, now we have no idea what the answer is.

yup its def 12
