10. What is the least number of acute angles a triangle can have?
11. Can a triangle have a right angle and an obtuse angle? Explain your answer.
12. Kaya said that a rectangle can be a rhombus. Explain whether Kaya's statement is correct.
13. Andy said that a quadrilateral can have exactly 3 right angles. Explain whether Andy's
statement is correct.

idk about 12 and 13 but the number of acute angles a triangle can have is 2 and for 11 No, a triangle cannot have an obtuse and a right angle.

Step-by-step explanation:

10) 3

11) no

12) kayla's statement is incorrect because the diagonals of a rectangle do not intersect each other at 90 degree like a rhombus.

13) Andy’s statement is incorrect because

Quadrilaterals have 4 sides and 4angles. The exterior angles of any convex polygon add up to 360 degrees ( 4 right angles). If an interior angle is a right angle then the corresponding exterior angle must also be a right angle

Step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.
