really need help on these two questions for geometry, please actually answer it instead of just grabbing points and leaving :'),
egoroff_w [7]

Answer:

Step-by-step explanation:

The diagonals of a rhombus are perpendicular, so ∠AED = 90° and ∠BEC = 90°.

∠DAE = 180° - ∠AED - ∠EDA = 180° - 90° - 35° = 55°

BD is a transversal across parallel sides AD and BC, so ∠EBC = ∠EDA = 35°.

∠BCE = 180° - ∠BEC - ∠EBC = 180° - 90° - 35° = 55°

Marco puts his coins into stacks. Each stack has 10 coins.
Harrizon [31]

Answer:

Marco has $57.50 in total.

Step-by-step explanation:

17 x 10 = 170 quarters

170 x 0.25 = $42.50

11 x 10 = 110 dimes

110 x 0.10 = $11.00

8 x 10 = 80 nickels

80 x 0.05 = $4.00
