Answer:

  26.0 cm

Step-by-step explanation:

Given quadrilateral ABCD with diagonal BD forming triangles ABD and BCD, and angles A=90°, C=52°, ADB=35°, and CBD=52°, you want the length of CD to 3 significant figures.

<h3>Law of Sines</h3>

The law of sines tells you the relation between sides and opposite angles is ...

  a/sin(A) = b/sin(B) = c/sin(C)

This lets us write two proportions that can be solved for the measure of CD.

In triangle ABD:

  BD/sin(A) = AB/sin(D)

  BD = AB·sin(90°)/sin(35°) = 12 cm/sin(35°) ≈ 20.921 cm

In triangle BCD:

  CD/sin(B) = BD/sin(C)

  CD = BD·sin(B)/sin(C) = 20.921 cm·sin(102°)/sin(52°) ≈ 25.969 cm

The length of CD is about 26.0 cm.

How do i solve 3x-5y=9;x=-1,0,1
REY [17]
For x = -1, 3(-1) - 5y = 9 => -3 - 5y = 9 => 5y = -3 - 9 = -12 => y = -12/5 = -2.4
for x = 0, 3(0) - 5y = 9 => -5y = 9 => y = 9/-5 = -1.8
for x = 1, 3(1) - 5y = 9 => 3 - 5y = 9 => 5y = 3 - 9 = -6 => y = -6/5 = -1.2
