To change a division of fractions to a multiplication problem, you multiply by the reciprocal of one of the numbers (use the KFC rule of Keep, Flip, Change). Keep 7/9, flip the sign (division to multiplication), and change 3/8.

Johnetta should have done 7/9 times 8/3, which would be 56/27.

Right triangles abc and bcd with right angle c are given below. if m(a)=30∘,m(d)=45∘, and bd=12, find the length of ab. note: th

vesna_86 [32]

Solution:

A is the right tringle ABD, C is bisects AD.

AC = CD and BD = 12

BC=BDsin(BDC)

BC=12Sin(45)

$=12\times \frac{1}{\sqrt{2}}=\frac{12}{\sqrt{2}}$

$AB=\frac{BC}{sin(bac)}=\frac{\left | 2 \right |\sqrt{2}}{sin30}=\frac{\left | 2 \right |\sqrt{2}}{\frac{1}{2}}=\frac{12\times 2}{\sqrt{2}}$

$AB=\frac{24}{\sqrt{2}}=12\sqrt{2}$

PLEASE HELP!!! ILL GIVE BRAINLIEST!

Answer: Last Option (Red In Colour)

Reason: Since Point Slope Form is y -y1 = m(x-x1), We just plug in the numbers. Four will go into the x1 spot, and Zero will go into the y1 spot, and 1/2 in the m spot since it's the slope. So, after plugging everything in, the equation is y - 0 = 1/2 ( x- 4)
