Answer:
(i) ∠CDF = 86°
(ii) ∠BAD = 141°
Step-by-step explanation:
(i) Angles CDF and GFD are "alternate interior" angles, so are congruent.
∠CDF = 86°
__
(ii) Angles BAD and CDA are "alternate interior angles, so are congruent. Angle CDA is the sum of angles CDH and HDA. Angle CDH is supplementary to angle CDF, so is ...
∠CDH = 180° -∠CDF = 180° -86° = 94°
Then ...
∠CDA = ∠CDH +∠HDA = 94° +47°
∠CDA = 141°
I believe the answer is 2/1, or 2 over 1.
The number of sixty-minute cassette tapes ordered is 288 and the number of CDs ordered is 163.
<h3>What are the linear equations that represent this question?</h3>
1.49a + 4.98b = $1240.86 equation 1
a + b = 451 equation 2
Where:
- a = number of sixty-minute cassette tapes ordered
- b = number of CDs ordered
<h3>How many
CDs were ordered?</h3>
Multiply equation 2 by 1,49
1.49a + 1.49b = 671.99 equation 3
Subtract equation 3 from equation 1
568.87 = 3.49b
Divide both sides of the equation by 3.49
568.87 / 3.49
b = 163
