Answer:
1. A = 59
2. A = 43
Step-by-step explanation:
If we have a right triangle we can use sin, cos and tan.
sin = opp/ hypotenuse
cos= adjacent/ hypotenuse
tan = opposite/ adjacent
For the first problem, we know the opposite and adjacent sides to angle A
tan A = opposite/ adjacent
tan A = 8.8 / 5.2
Take the inverse of each side
tan ^-1 tan A = tan ^-1 (8.8/5.2)
A = 59.42077313
To the nearest degree
A = 59 degrees
For the second problem, we know the adjacent side and the hypotenuse to angle A
cos A = adjacent/hypotenuse
cos A = 15.3/21
Take the inverse of each side
cos ^-1 cos A = cos ^-1 (15.3/21)
A = 43.23323481
To the nearest degree
A = 43 degrees
First, add '5' to both of the sides.
Second, add '3 + 5' to get 8.
Third, multiply both sides by '4' to get rid of the fraction.
Fourth, multiply '8 × 4' to get '32'.
Fifth, you can switch your sides.
Answer:
<u>Answer:</u>
Supplement of 84° is 96°
Complement of 54° is 36°
<u>Step-by-step explanation:</u>
1<u>) A supplementary angle is two angles that add up to 180°</u>
so to find the supplement of 84° ⇒ 180°- 84° = 96°
2) <u>A complementary angle is two angles that add up to 90°</u>
so to find the complement of 54° ⇒ 90°- 54° = 36°
The pattern is going by six, so every time it goes up by six. Therefore, the next number is 158
