I think by SAS because there is only one angle and two sides
Given:
m is directly proportional to the cube of h.
m = 525 when h= 5.
To find:
The equation connecting m and h.
Solution:
m is directly proportional to the cube of h.
...(i)
Where, k is the constant of proportionality.
Putting m = 525 and h= 5, we get
Putting k=105 in (i), we get
Therefore, the required equation is .

Answer: 12) 34° 13) 90°
<u>Step-by-step explanation:</u>
12) Given: a = 10.2, b = 6.8, A = 122°
*****************************************************************************
Law of Cosines: a² = b² + c² - 2bc · cos A
<em>Note: The letters can be swapped</em>
13) Given: a = 3, b = 4, c = 5, C = ???
3² = 4² + 5² - 2(4)(5) · cos C
9 = 16 + 25 - 40 cos C
9 = 41 - 40 cos C
-32 = -40 cos C
0.8 = cos C
90° = C
Answer: y=24
Step-by-step explanation:180-49=131 131-32=96, 96 devided by 4 is 24
