Find the unknown angles in the following right triangle by using trigonometric ratios.

Answer: C

Step-by-step explanation:

a = 3 and b = 2...........

Answer:

3

Step-by-step explanation:

RS + ST will equal RT.

So, 2 + 3x must equal 5x.

2+3x = 5x

2 = 2x

x = 1

ST = 3x

ST = 3*(1)

ST = 3

Answer:

x=1

Answer:

W X = 83

W Y = 119

X Y = 36

Step-by-step explanation:

W X = 3y + 11

W Y = 6y - 25

X Y = y + 12

Answer:

x=116

Step-by-step explanation:

180-C will get you F since they are adjacent angles, which would be 116.  We know that the opposite angles of a parallelogram are equal, so x=116

Answer:

2x(x+1)(5x+7)

Step-by-step explanation:

10x^3+24^2+14

2(5x^3+12x+7)

2x(5x^2+12x+7)

2x(x+1)(5x+7)

2x(2x+1)(5x+7)

Answer:

the square root of d

Step-by-step explanation:

if [tex]u^{2} = d[/tex] then the square root property would take the square root of each side of the equation. the square root of [tex]u^{2}[/tex] would just be [tex]u[/tex] because it's already squared and its exponent would just be cancelled out, while d would simply turn to [tex]\sqrt{d}[/tex].

meaning if [tex]u^{2} =d[/tex] then [tex]u=\sqrt{d}[/tex], because you've done the same thing to both sides of the equal sign, so they remain equivalent.

The square root property says the value of u²=d is u=±√d

The square root of a number is defined as the value, which gives the number when it is multiplied by itself. The radical symbol √ is used to indicate the square root. For example, √16 = 4. The radical symbol is also called a root symbol or surds.

Given here: The expression u²=d

The square root of a number is a value, which on multiplication by itself, gives the original number. The square root is an inverse method of squaring a number. To indicate that we want both the positive and the negative square root of a radicand we put the symbol ± (read as plus minus) in front of the root.

Thus we have the given expression as u²=d

Taking square root on  both sides we get u=±√d

Hence, The square root property says the value of u²=d is u=±√d

Answer:

B. (2x + 3y)(x - y)

Step-by-step explanation:

[tex]2x^{2} +xy-3y^{2}[/tex]               Write x y as a difference

[tex]2x^{2} +3xy-2xy-3y^{2}[/tex]    Factor out x from the equation

[tex]xx(2x+3y)-yx(2x+3y)[/tex]   Factor out 2x+3y from the expression

[tex](2x+3y)x(x-y)[/tex]               <----- Answer

The factors of  [tex]2x^2 + xy - 3y^2[/tex] are [tex](x - y) (2x+ 3y)[/tex].

Factors is a number or algebraic expression that divides another number or expression. i.e., with no remainder

We have,

[tex]2x^2 + xy - 3y^2[/tex]

Now,

Using the middle term split method,

[tex]2x^2 + xy - 3y^2[/tex]

Splitting the mid term;

[tex]2x^2 - 2xy + 3xy - 3y^2[/tex]

Now taking commons,

[tex]2x(x - y) + 3y(x - y)[/tex]

Now again taking common factors

We get,

[tex](x - y) (2x+ 3y)[/tex]

So, the factors of given expression are [tex](x - y) (2x+ 3y)[/tex].

Hence, we can say that the factors of  [tex]2x^2 + xy - 3y^2[/tex] are [tex](x - y) (2x+ 3y)[/tex] which are given in option [tex](B)[/tex] .

The equation of a line that represents the table is; y = 6x - 5.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b. Where slope = m and b = y-intercept.

Since we know that the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

To find the linear equation first we need slope;

(m) = (y₂ - y₁)/(x₂ - x₁)

= (1 + 11)/(1 + 1) = 12/2

m = 6.

Now, we have to take any one of these coordinate points and construct an equation in slope-intercept form;

- 11 = 6(-1) + b.

- 11 = - 6 + b.

b = - 5.

Therefore,  y = 6x - 5 is our equation. the correct table represent a linear relationship is 2nd.

Answer:

p=7

Step-by-step explanation:

Let's solve your equation step-by-step.

3+5p−12=2p+12

Step 1: Simplify both sides of the equation.

3+5p−12=2p+12

3+5p+−12=2p+12

(5p)+(3+−12)=2p+12(Combine Like Terms)

5p+−9=2p+12

5p−9=2p+12

Step 2: Subtract 2p from both sides.

5p−9−2p=2p+12−2p

3p−9=12

Step 3: Add 9 to both sides.

3p−9+9=12+9

3p=21

Step 4: Divide both sides by 3.

Answer:

2.3

Step-by-step explanation:

This is quite simple; just find out how many feet are in 1 yard, then multiply it to yards.

Solve

Given: 7 feet giraffe

To find: 7 feet in yards

First, 1 foot = 0.3 yards

∴, 7 feet = 1/0.3 × 7/?

Multiply 0.3 and 7
