What is the value of m in the figure below? if necessary round your answer to the nearest tenth of a unit

m=6.7

Step-by-step explanation:

It turns out from similar triangles, that 3/BD = BD / 12. Use triangles  ABD and BDC to show this relationship. Solving this equation will give you BD

BD² = 3*12

BD² = 36     Just leave it in this form. Do your rounding at the end.

Because triangle BDC is a right angle triangle, use the Pythagorean Theorem to solve for m

m² =  BD^2 + 3^2

m² = 36 + 9

m² = 45                        

Take the square root of both sides.

√m² =√45

m=6.7082039325

m=6.7

Thus the correct option is A

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

24/56=hx^7
