The greatest common factor would be 3 as 15/3 = 5 and 27/3 = 7, cannot get simpler than that!!
Answer:
Step-by-step explanation:
First thing I would do is square the 14, and put it under the radical. Itll make the calculations a little bit easier.
14sqrt(2) = sqrt392
Use the definition of sine to find the value of a
sin(45) = opposite/hypotenuse = a/sqrt392
a = 14
Answer:
Hi... Your answer is... B
She can use 2x5 because that is the commutative property. commutative property of multiplication states that two numbers can be multiplied in either order, for example, 3x15 can also be multiplied in this way: 15x3. they will both make the same answer: 45
<em>Answer:</em>
<em>y = 49°</em>
<em />
<em>Step-by-step explanation:</em>
<em>∠DBC = ∠CBD { BC = DC ; angles oppostie to the equal sides are equal}</em>
<em />
<em>∠DBC + ∠CBD + ∠C = 180 {angle sum property of triangle}</em>
<em />
<em> y + y +82 = 180</em>
<em />
<em> 2y = 180 - 82</em>
<em />
<em> y = 98/2 = 49</em>
