In the figure at right, BC = 10. Find AC.

i dont know

Step-by-step explanation:

Step-by-step explanation:

angle(A+B+C)=180°{sum of angle of triangle}

C=180°-135°

C=45°

now,

sin theta=p/h

sin 45°=10/AC

1/√2=10/AC

AC=10√2

Ac=14.14

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
