Answer:
a) ∠A = 82.2° , ∠C = 62.8° , c = 17.01
Step-by-step explanation:
<u><em>Explanation</em></u>:-
<u><em>Step(i)</em></u>:-
Given data ∠B measures 35° and the values of a and b are 19 and 11
∠B = 35° and sides a = 19 and b = 11
<em>By using sine rule </em>
<em></em><em></em>
now we will use
cross multiplication , we get
<em>sin A = 0.990</em>
<em>A = sin⁻¹( 0.990) = 82.2°</em>
<em> ∠A = 82.2°</em>
<u><em>Step(ii):-</em></u>
we know that ∠A +∠B +∠C = 180°
∠C = 180° - ∠A -∠B
∠C = 180° -82.2°-35°
∠C = 62.8°
<u><em>Step(iii)</em></u>:-
<em>we will use formula</em>
<em></em><em></em>
<em></em><em></em>
<em>c = 17.01</em>
<u><em>Final answer</em></u>:-
<em> ∠A = 82.2° , ∠C = 62.8° , c = 17.01</em>
Given:
The table of values.
Hours (h) Dollars (d)
1 42
2 84
3 126
4 168
5 ?
To find:
The correct statements about the table.
Solution:
From the given table it is clear that,
This pattern can be defined as
Multiply h by 42 to get d. So, option A is correct.
Using this pattern, we get
The missing value in the last row is 210. So, option D is correct.
From the given table it is clear that the rate of change is $42 per hour because dollar is increasing by 42 in every hour.
A real-world situation that is represented in the table is “Richard is a video game designer and earns $42 per hour.”
Therefore, the option E is correct.
