HELP!! Find the value of x in the triangle!! 20PTS!!

Answers

Answer:

x = 5°

Step-by-step explanation:

We know that in a triangle, the measure of an exterior angle is equal to the sum of its two remote interior angles, therefore:

7x + 4 + 61 = 20x

7x + 65 = 20x

13x = 65

x = 5°

Answer:

Solution given:

61°+(7x+4)°=20x [ exterior angle is equal to the sum of two opposite interior angle]

65+7x=20x

65=20x-7x

13x=65°

x= $(65)/(13)$ =5°

value of x=5°

Write the following sentence using mathematical symbols. The sum of 10 and x is -13. "The sum of 10 and x is -13" in mathematical symbols is..

Answers

The equation for the given phrase is 10+x=-13 and the solution is x=-23.

The given phrase is "The sum of 10 and x is -13".

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Here, the sum of 10 and x is 10+x.

Now, the equation is 10+x=-13

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

The solution is x=-13-10 (Transpose 10 to other side of the equation)

x=-23

Therefore, the equation for the given phrase is 10+x=-13 and the solution is x=-23.

2. 4x - 2y = -6
-6x + 2y = 2

Answers

Answer:

x = 2, y =7

Step-by-step explanation:

4x - 2y = -6

-6x + 2y = 2

Add the equations together

4x - 2y = -6

-6x + 2y = 2

-----------------------

-2x = -4

Divide each side by -2

-2x/-2 = -4/-2

x = 2

now find y

-6x+2y =2

-6(2) +2y =2

-12+2y =2

Add 12 to each side

-12+12+2y = 2+12

2y =14

Divide by 2

2y/2 =14/2

y =7

Answers

Answer:52°

Step-by-step explanation:

x+x+14=90

Collect like terms

x+x=90-14

2x=76

Divide both sides by 2

2x/2=76/2

x=38

angle (x+14)°=(38+14)°=52° which is vertically opposite to angle PKQ.

Since Vertically opposite angles

Therefore angle PKQ=52

Write the ordered pair that represents y. Then find the magnitude of y.14-2,5), 2(1, 3)

a. (3. - 2); „13 units

C. (3. - 2); 2-5 units

b. (1,5): V13 units

d. (1,5); 2-7 units

Answers

Answer:

(3,-2), $√(13) }$ units

Step-by-step explanation:

the correct question is:

Write the ordered pair that represents yz. Then find the magnitude of yz . y(-2,5),z(1,3)

SOLUTION:

points given are y(-2,5) and z(1,3)

$^( \to) _(YZ) = \binom{1}{3} - \binom{ - 2}{5} = \binom{3}{ - 2}$

so, the ordered pair is (3,-2)

next is to find the magnitude:

$|^( \to) _(YZ)| = \sqrt{ {3}^(2) + ( - 2)^(2) }$

$|^( \to) _(YZ)| = √( 9 +4)$

$\n|^( \to) _(YZ)| = √(13) }$ units
