Answer:
72 pi + 48 pi= 120pi (not sure if I am right tho)
Step-by-step explanation:
The 2 angles form a linear pair and angles that form a linear pair have a sum of 180 so
10x + 15 + 5x = 180
15 + 15x = 180
180 - 15 = 15x
165 = 15x
11 = x

Step-by-step explanation:
Answer: AB=85
Step-by-step explanation:
Question 1:
To start off this question, we can tell that this is a square because it has 4 right angles and 4 congruent sides.
A square has four parallel sides and 4 congruent sides, so a square is a rhombus and parallelogram.
A square has 4 right angles, so it's also a rectangle.
A square has 4 sides, so it's also a quadrilateral.
The first choice is your answer.
Question 2:
Not all quadrilaterals are rectangles, so A is incorrect.
Not all quadrilaterals are squares, so B is incorrect.
All rectangles are types of quadrilaterals, so C is correct.
Not all quadrilaterals are parallelograms, so D is incorrect.
Thus, C is your answer.
Question 3:
The first choice will not work because a rhombus will satisfy those conditions, and a rhombus is not always a square.
The second choice will work because only a square will satisfy that condition because only squares have 4 congruent sides along with equal diagonals.
Thus, the second choice is your answer.
Have an awesome day! :)
