What is angle 1 and 2 to each other and how can you tell

1 answer:

6 0

Angles 1 and 2 are adjacent angles. You can tell because adjacent means right next to each other, which they are. If they were a linear pair, they'd have to be adjacent to eachother on a line.

Question 9

True [87]

Answer:

Step-by-step explanation:

m<1 = (4x + 2)

m<3 = (5x - 15)

To find the value of x, we need to generate an equation.

<1 and <3 are vertical angles. Vertical angles are congruent. Therefore:

m<1 = m<3

(4x + 2) = (5x - 15)

Use this equation to solve for x

4x + 2 = 5x - 15

Subtract 5x from both sides

4x + 2 - 5x = 5x - 15 - 5x

-x + 2 = -15

Subtract 2 from both sides

-x + 2 - 2 = -15 - 2

-x = -17

Divide both sides by -1

x = 17

The lengths of three sides of a triangle are in the ratio 3 : 4 : 5. The perimeter of the triangle is 156 centimeters. What is t

julsineya [31]

3x + 4x + 5x = 156

12x = 156

x = 13

3*13 = 39

5*13 = 65

65-39=26 cm difference

Answer:

Step-by-step explanation:

12/8 = 1.5

21.6/14.4 = 1.5

18/12 = 1.5

the AA postulate states that two triangles are similar if they have two corresponding angles that are congruent or equal in measure
