Answer:

1) ∠A = 90º Square

2) ∠A = 140º Parallelogram

3) ∠A = 90º Rectangle

4) ∠A = 95º Rhombus

5) ∠A = 60º Trapezoid

6) ∠A = 41º Parallelogram

Step-by-step explanation:

There just some points I want to state:

Rhombus is a quadrilateral with all sides being equal and opposite sides being parallel. Also, the opposite angles are equal, and the the diagonals bisect each other at right angles (90º).

In order to find the angles, just consider:

Sum of internal angles = 360º

You may also note the complementary and supplementary angles.

Jeremy used a total of 16 sticks to support his vegetables. The sticks were 55cm and 75cm long and the sum of their lengths was

svetoff [14.1K]

9 longer sticks were used.
This is how i get it.
1. change m to cm, 1m =100cm
2. add both together, divide by 16 =8.125. Which means 1 of the stick should more than 8, and 1 of the other stick should be less than 8
3. substitute the equation
4.(55 x 7)+(75 x 9) =1060
