Substitute 3 into the expression for m, and 7 into it for n. So 3mn = 3(3)(7) = 3 x 21 = 63.

4.7244m

convert feet to inches using 1 foot = 12 inches

15.5 feet = 15.5 × 12 = 186 inches

multiply this by 2.54 to convert to cm

186 inches = 186 × 2.54 = 472.44 cm

now 1m = 100cm

divide 472.44 by 100 to convert to m

472.44 ÷ 100 =4.7244m

Someone please solve. I keep getting 66 but it's wrong.​
sashaice [31]

The unlabeled part of the right angle is complementary to 68 degrees, so 22 degrees. y is supplementary to 78 degrees, so 102 degrees.  z as the third angle in the small triangle is 180 less than the sum of the other two,

z = 180 - 22 - 102

Answer: 56 degrees

In triangle NQL, point S is the centroid, NS = (x + 10) feet, and SR = (x + 3) feet.
olya-2409 [2.1K]
Where R is the median between Q and L:

From my understanding of a triangle's centroid, it divides an angle bisector into parts of 2/3 and 1/3. In the given problem, these divisions are NS and SR. Therefore, twice SR would be equal to NS. From here, we can get the value of X, to solve for SR.

NS = 2SR
(x + 10) = 2(x + 3)
x + 10 = 2x + 6
x = 4

Therefore, SR = (x + 3) = 7
