Answer:

x° = 123

Step-by-step explanation:

this triangle is isoceles so it has 2 congruent angles.

let y be the second angle

the sum of a triangle's angle is 180°

[tex]180 = 66 + y + y \\180 = 66 + 2y[/tex]

add [tex]-66[/tex] to both sides

[tex]180 - 66 = 2y + 66 - 66 \\114 = 2y[/tex]

divide both sides by 2

[tex]\frac{114}{2} = \frac{2y}{2}[/tex]

[tex]57 = y[/tex]

we khow that [tex]x + y = 180[/tex]

[tex]x + y = 180 \\x + 57 = 180[/tex]

add -57 to both sides

[tex]x + 57 - 57 = 180 - 57 \\x = 123[/tex]

Answer:

Many solutions

Step-by-step explanation:

First, you distribute the 6 into the parenthesis:

4x+6=6(x+1)-2x

4x+6=6x+6-2x

4x+6=4x+6

subtract 6 from both sides

4x=4x

All real numbers can be the solution

Answer:

so x = 20 , y = -21 , which is in quad IV

r^2= 400+441 = 841

r = √841 = 29

then cos Ø = 20/29

sec Ø = 29/20 = 1.45

The exact value of cos [tex]\theta[/tex] is 21/29.

One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.

We have, point (21, 20)

So, Adjacent side= 21 and opposite side= 20

Using Pythagoras theorem

H= √ 21²  + 20²

H= √441 + 400

H= √841

H= 29 unit

So, the trigonometric ratio

cos [tex]\theta[/tex] = Adjacent side/ H

cos [tex]\theta[/tex] = 21/29

Thus, the exact value of cos [tex]\theta[/tex] is 21/29.

Answer:

27.9

Explanation:

As you can see they both have an absolute value because they are both in between the 2 lines. So you have to change both of them into a positive number. You would get 5.9+22 which would equal 27.9

Answer:

y = x + 14

Step-by-step explanation:

given

5x−5y=−2, we'll rearrange this into slope - intercept form

5x + 2 = 5y

5y = 5x + 2    (divide both sides by 5)

y = x + (2/5)

recall that the general equation of the slope-intercept form of a linear equation:

y = mx + b, the value of m represents the slope of the line

in our case, comparing the above equations, it is clear that the slope m = 1.

We are given that our line is parallel to the above line, hence it will also have  a slope of 1.

if we substitute m = 1 into the general equation, we will get

y = x + b

in order to find the value of b, we will substitute the given point (-10,4) into the equation:

4 = -10 + b   (add 10 to both sides)

b = 4 + 10

b = 14

hence our equation is y = x + 14
