Answer:
43
Step-by-step explanation:
we know that ABC and CBD need to add up to 90 so we have
47+CBD=90
CBD=43
Question 1: Option D
Area of the parallelogram = 132 cm²
Question 2: Option B
Area of the parallelogram = 3.60 ft²
Solution:
Question 1:
Base of the parallelogram = 6 + 5 = 11 cm
Height of the parallelogram = 12 cm
Area of the parallelogram = Base × Height
= 11 × 12
Area of the parallelogram = 132 cm²
Option D is the correct answer.
Question 2:
Base of the parallelogram = 1.9 + 0.5 = 2.4 ft
Height of the parallelogram = 1.5 ft
Area of the parallelogram = Base × Height
= 2.4 × 1.5
Area of the parallelogram = 3.60 ft²
Option B is the correct answer.
According to the law of sines:

Using the given values, we can find the angle B and find the number of possible triangles that can be formed.

The range of sin is from -1 to 1. The above expression does not yield any possible value of B, as sin of no angle can be equal to 1.45.
Therefore, we can conclude that no triangle exists with the given conditions.
Sorry sir... but the screen is blurry. ; u ;
