△ABC is a right triangle. m∠A = 32° m∠B=90°; AC = 9 and AB=5. Choose the expression used to find BC?
Westkost [7]

Answer:

Step-by-step explanation:

The diagram of the right angle triangle is shown in the attached photo.

From the given right angle triangle,

AC represents the hypotenuse of the right angle triangle.

With m∠32 as the reference angle,

BC represents the adjacent side of the right angle triangle.

AB represents the opposite side of the right angle triangle.

To determine BC, we would apply

the Sine trigonometric ratio which is expressed as

Sin θ= opposite side/hypotenuse. Therefore, the expression used to find BC is

Sin 32 = BC/9

BC = 9Sin32

Erika is working on solving the exponential equation 50x = 17; however, she is not quite sure where to start. Using complete sen
Liono4ka [1.6K]

Answer:

Step-by-step explanation:

Divide both sides by 50 and you'll get x=17/50

If x is the exponent than we can take the natural log of both sides.

x(ln)50=ln(17)

Then divide ln50 on both sides

x=ln17/ln50= 0.72423228087

Triangles ABC and DEF similar
Anarel [89]

Answer:

DE = 4 1/2

EF = 3 3/4

Step-by-step explanation:

AB/AC = DE/DF

6/4 = DE/3

cross-multiply:

4DE = 18

DE = 18/4 or 4 1/2

AB/BC = DE/EF

6/5 = 4.5/EF

cross-multiply:

6EF = 22.5

EF = 3.75
