Answer 1

Answer:

Answer:

1) option c

2) option d

3) option a

4) option a

5) option c

Step-by-step explanation:

1. Given that in ΔRST, ∠R=63°, ∠T=90° and so ∠S=27°

Also, cosec=hyotenuse/opposite side

Given RS=23 and ST=10.4

So, cosec27=RS/RT=23/RT

sec=hypotenuse/adjacent side

sec27=RS/ST=23/10.4

And cot=adjacent/opposite side

So, cot63=RT/ST=RT/10.4

2. formula:- sinθ=opposite side/hypotenuse

cosecθ=hypotenuse/opposite side

∴ sinθ *cosecθ = (opposite side/hypotenuse) * (hypotenuse/opposite side) = 1

3. Formula :- tan(360-θ) = -tanθ

∴ tan(300) = tan(360-60) = -tan30°

tan30° = √3

∴tan300° = -√3

5. sinθ= opposite side/hypotenuse

cosecθ = hypotenuse/opposite side

∴ cosecθ = 1/sinθ

Given sinθ = 0.3090

∴ cosecθ = 1/0.3090 = 3.2362

Tell what whole number you can substitute for xx in the following list so the numbers are ordered from least to greatest. 1/x,x/3,80%

Answers

Answer:

Take x = 2.

Step-by-step explanation:

We have,

The numbers are $(1)/(x),(x)/(3),0.8$ .

We need to find the value of x such that they are ordered from the least to the greatest.

Let us take, x = 2.

So, we get,

$(1)/(x)=(1)/(2)=0.5$

$(x)/(3)=(2)/(3)=0.6$

As, 0.5 < 0.6 < 0.8.

Thus, taking x = 2 gives the desired result.

x/3 has to be smaller tha 80%
so x can be 2 since 2/3=66% about
1/2 is less thn 2/3

answer is x is 2

What is the area of this circle with center c, rounded to the nearest tenth?

Answers

The equation for the area of a circle is:

A = \pi r^{2}

The diameter of the circle is 44cm, to get the radius you divide the diameter by 2, or the radius is half of the diameter

\frac{d}{2} = r

\frac{44}{2} = r

22 = r

Now that you have r, you can plug it into the equation

A = \pi (22)^{2}

A = \pi (484)

A = 1520.5 cm²

The answer would be closest to the first multiple choice answer

Answer: -a - 2b -9c

Step-by-step explanation:

-2a - (-a) = -a

-4b - (-2b) = -2b

-6c - (3c) = -9c

-a - 2b - 9c

What is the area of the rectangle? Round to the nearest square inch.A.
27 in2

B.
31 in2

C.
45 in2

D.
47 in2

Answers

The area of a rectangle is expressed the product of its length and its width. For this rectangle we are given only its width and its diagonal. Thus, we need to solve for its length. A diagonal is a line that divides the rectangle making two right triangles. We can solve its length by using the diagonal. Calculations are as follows:

cos 45 = Length / 8
Length = 4√2 in

Area = (4√2)(5) = 20√2 in

Does anyone know how to do this

Answer:

m+n=140

Step-by-step explanation:

While it may seem you need to find the measure of m and n, you don't. Looking at the angle with measure of 40 degrees you can see inside the triangle that the top angle is congruent to the angle of 40 degrees. Now that you know that the top of the angle is 40 degrees then knowing a triangle is 180 degrees total you can infer that m+n=140 because adding 140 to 40 is also 180.
