b. sin 43°
c. tan 43°
d. cos 133°
B.....
cos (47°)= sin (90°-47°)=sin (43°) [complementary angles]
Answer B

6 - 2 = 4
Answer: B.The cost of rental fee only
Step-by-step explanation:
The $35 is the cost of the rental fee only. The person would then have to pay a further $15 for every hour they use the boat.
Essentially, the $35 is the fixed cost associated with the rental and the $15 is the variable cost to do so. If this were in a linear equation format it would take the form: y = 15x + 35.
If you can find one leg of a triangle to be congruent to a leg on the other triangle, then you can use the HL (hypotenuse leg) theorem. If the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent.
<h2><u>Answer:-</u></h2>
Given:
Two angles form a linear pair.
It means sum of their measures = 180°.
And,
Measure of one angle is 24° greater than the other.
Let the other angle be x.
→ First angle = (x + 24)
According to the question,
<h3>→ x + x + 24 = 180</h3>
→ 2x = 180 - 24
→ 2x = 156
→ x = 156/2
<h3>→ X = 78°</h3>
<u>There</u><u>fore</u><u>,</u>
- 1st angle = 78°
- 2nd angle = 78° + 24° = 102°
