13 x 6 = 78 it cant be multiplied anymore so it can go into 80 about 6 times.
From the equilateral (60-60-60) triangle with all legs of length 1, we can view half the triangle, forming a 30-60-90 triangle, with the hypotenuse measuring 1, the short leg1/2<span>, and the long leg 3 2. Therefore, we have sin 30° = </span>1/2<span>, cos 30° = 3 2, sin 60° = 3 2 and cos 60° = </span>1/2<span>.
i hope this help</span>
Answer:
Step-by-step explanation:
Bring out the common factor of <em>4 </em>from the equation
9 and 225 share a common factor of 9. Factor the 9 out
well first he should have multiplied 1 and 3 then 3 and 3 then added them up and multiplied the 5 by 5 and made it into this 2(3+9) -25 this would have became 2(12) -25 witch the would be 24-25 and then became -1
