Answer:

Step-by-step explanation:

Using the triangular law which states that the sum of interior anggle of a triangle is equal to exterior angle

From the diagram

Interior angles = 5x +10 and 58

Interior angle = 11x+2

Equate both expressions

5x + 10 + 58 = 11x+2

5x - 11x = 2 - 10 - 58

-6x = 2-68

-6x = -66

x = -66/-6

x = 11

<em>Hence the value of x is 11</em>

a triangle has vertices at (1, 1), (1, 2), and (3, 2). it is dilated by a scale factor of 3 within the origin as the center of d

PolarNik [594]

Answer:

(3,3), (3,6), (9,6)

Step-by-step explanation:

A triangle ABC has vertices at A(1, 1), B(1, 2), and C(3, 2).

The dilation by a scale factor of 3 within the origin as the center of dilation has the rule

$(x,y)\rightarrow (3x,3y)$

Hence,

$A(1,1)\rightarrow D(3,3)$
$B(1,2)\rightarrow E(3,6)$
$C(3,2)\rightarrow F(9,6)$

See attached diagram for details.

Simplify fully<br> 2√3 x 3√8

OverLord2011 [107]

Answer: 12√6

Step-by-step explanation:

Given the expression;

2√3 * 3√√8

= (2*3) * (√3*√8)

= 6 * (√24)

= 6 * √4*6

= 6 * (2√6)

= (6*2)√6

= 12√6

Therefore, the simplified form of the expression is 12√6.

∠1 and ∠2 are a linear pair, and ∠2 and ∠3 are vertical angles. m∠2=(5+4y)∘ and m∠3=(6y−25)∘

Leni [432]

Answer:

The measure of angle 1 is 115°

Step-by-step explanation:

we know that

If ∠1 and ∠2 are a linear pair

then

∠1 +∠2 =180° -----> supplementary angles

If ∠2 and ∠3 are vertical angles

then

∠2 =∠3

step 1

Find the value of y

we know that

∠2 =∠3

substitute values

(5+4y)°=(6y-25)°

6y-4y=(5+25)°

2y=(30)°

y=15°

step 2

Find the measure of angle 2

∠2=(5+4y)°

substitute the value of y

∠2=(5+4(15))°

∠2=65°

step 3

Find the measure of angle 1

we know that

∠1 +∠2 =180°

we have

∠2=65°

substitute

∠1 +65°=180°

∠1 =180°-65°=115°

Answer:

The distance between ring and coin is 13 units apart.

Step-by-step explanation:

$\sqrt{ {(x1 - x2)}^{2} + {(y1 - y2)}^{2} }$

Using this formula, you are able to find the distance between the ring and the old coin :

Let (x1,y1) be (10,19),

Let (x2,y2) be (5,7),

D = √(10-5)²+(19-7)²

= √5²+12²

= √25+144

= √169

= 13 units
