Answer::

Angle 3 is the interior adjacent angle.

Step-by-step explanation::

Any two interior angles that share a common side are called the adjacent interior angles.They have the same vertex  and have a common arm.

Angle 4 is adjacent exterior angle with angle 3 but 3 is internal.

So, the answer is angle 3.

<u>Answer</u>

3


<u>Explanation</u>

Adjacents angles are angles that have the same vertex and do not overlap.

In the diagram the adjacent angles are 3 and 4.

The interior angles from the diagram are 1, 2, and 3.

4 is an exterior angle.


So, the adjacent interior angle is 3.

Answer:

there are fourteen 4-point questions and twenty six 2-point questions.

Step-by-step explanation:

Given : A 40-question test has 108 possible points.

There are m 4-point questions and n 2-point questions.

So , equation for total number of questions in the test :

m + n = 40 | 4n + 2n = 108

Multiplying (i) by 2 , we get

2m + 2n = 80

Subtract (iii) from (ii) , we get

2m = 28

⇒ m = 28/ 2 = 14

Using value of m in (i) , we get

14 + n = 40 ⇒ n = 26

from this we get there are fourteen  4-point questions and twenty six 2-point questions.

hope this helped!

D

using the double - angle identity

cos (2A) = cos² A - sin² A = 2cos² A - 1 = 1 - 2sin² A

the right side = 1 - 2sin² (112.5° ) with A = 22.5°

hence 2A = 2 × 22.5° = 45°

thus cos 45° = 1 - 2sin² ( 22.5°)

Write the following as an algebraic expression. Then simplify.
Romashka [77]

Answer: A. 7x + 3

Concept:

Here, we need to know how to find the perimeter of a triangle

Perimeter (triangle) = s₁ + s₂ + s₃

s₁ = side one

s₂ = side two

s₃ = side three

Solve:

<u>Given information</u>

s₁ = 3x

s₂ = 3x + 3

s₃ = x

<u>Given expression</u>

P = s₁ + s₂ + s₃

<u>Substitute values into the expression</u>

P = (3x) + (3x + 3) + (x)

<u>Combine like terms</u>

P = (3x + 3x + x) + (3)

P = (6x + x) + 3

\boxed{P_{triangle}=7x+3}

Hope this helps!! :)
