Answer:
C.
Step-by-step explanation:
Cos A = Adj/Hyp
Reference angle = <A
Adjacent side = 8 ft
Hypotenuse = √(8² + 5²) = √89 (pythagorean theorem)
Thus:
Rationalize
Answer:
x = 28
y = 83
Step-by-step explanation:
We can use ratios to solve
18 21
------ = -------
24 x
Using cross products
18x = 24*21
Divide each side by 18
x = 24*21/18
x =28
The angles must be equal
<M = <I
83 = y
Answer:
No, because 5 + 4 isn't greater than 10.
Step-by-step explanation:

Do they form a triangle
To check if they form a triangle or not, we make use of trinagle inequality theorem which states that; for sides a, b and c
So for sides 4, 5 and 10, we have:
--- False
<em>Since the one of the inequalities is false, then the sides do not form a triangle.</em>
Answer:
Amrita = 14 years old
Aman = 6 years old
Step-by-step explanation:
Find out the difference of the units.
7 - 3 = 4
Amrita is 4 units/8 years older than Aman.
4 units = 8
1 unit = 8 ÷ 4 = 2
Amrita is 7 units and her brother is 3 units.
Amrita = 7 units x 2 = 14
Aman = 3 units x 2 = 6
