Answer:

  a) ∠DAE = 33°; ∠ABD = 57°

  b) ∠CEB = 90°

  c) ∠ABE = 22°

  d) ∠ADE = 15°

Step-by-step explanation:

The diagonals of a rhombus meet at right angles. Each bisects the corner angles at its ends. Adjacent angles are supplementary, opposite angles are congruent, and each diagonal creates two isosceles triangles.

a) ∠DAE = 90° - ∠ADE = 90° -57°

  ∠DAE = 33°

  ∠ADE = ∠ABD = 57°

__

b) ∠CEB = 90° . . . . . the diagonals meet at right angles

__

c) ∠ABE = 44°/2

  ∠ABE = 22°

__

d) ∠ADE = 90° -(1/2)∠DAB = 90° -150°/2

  ∠ADE = 15°

jeka57 [31]

we know that


The simple interest formula is equal to


A=P(1+rt)


where


A is the Final Investment Value


P is the Principal amount of money to be invested


r is the rate of interest  

t is Number of Time Periods


in this problem we have


t=9\ years\\ P=\$2,136\\ A=?\\r=0.0536


substitute in the formula above


A=2,136(1+0.0536*9)


A=2,136(1.4824)

A=\$3,166.41  

Round to the nearest dollar

A=\$3,166  

therefore

<u>the answer is the option D</u>

\$3,166
