Answer:

x ≈ 10.92

Step-by-step explanation:

Using the sine ratio in the right triangle

sin83° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{11}$

Multiply both sides by 11

11 × sin83° = x, thus

x ≈ 10.92 ( to 2 dec. places )

In trapezoid ABCD, AB ∥ CD , m∠A=90°, AD=8 in, DC=9 in, CB=10 in, and ∠B is acute. Find DB.

kiruha [24]

Answer:

the length of DB is 17 in

Step-by-step explanation:

Consider the sketch attached.

We will draw an imaginary line from point C to met line AB at point E.

A right-angled triangle will now be formed between points CBE.

The dimensions of the right-angled triangle will be:

CB = 10 in

CE= 8 in

EB = unknown

We will now proceed to find out the length of side EB using the Pythagoras' theorem.

$EB =\sqrt{CB^2 -CE^2} \\EB =\sqrt{10^2 -8^2} \\EB = 6 in$

From the shape, we can find out that another right-angled triangle is made between points DAB.

The dimensions of the triangle are:

DA= 8in

AB = 9 in + 6 in = 15 in

DB = unknown.

We will now proceed to find out the length of side DB using the Pythagoras' theorem.

$DB =\sqrt{AD^2 +AB^2} \\DB =\sqrt{8^2 +15^2} \\DB = 17 in$

Therefore, the length of DB is 17 in

Which measurement is not equal to 3 m 30 dm or 300 cm or 3000 mm or 3000 cm

Ainat [17]

3000cm because if you look at the variables there is no more letter m's than anything so if you cancel out and see what is equal to 30 then you get 3000cm!!!!!

I need help with a math question that is 0.1x = 5/y

BabaBlast [244]

Unfortunately you have not included the directions. Are you supposed to solve for x? or for y?

Suppose the directions say, "Solve for x." Then, clear out the decimal fraction by mult. both sides of the given equation by 10. This will give you the solution, that is, a formula for x in terms of y.
