Answer:
Step-by-step explanation:
we know that
The formula of law of cosines is equal to
where
a, b and c are sides. C is the angle opposite side c
In this problem we have
substitute the given values
(5/8) × 48 = (8/15) × n
Multiply by the inverse of the coefficient of n. That inverse is 15/8.
n = (15/8)×(5/8)×48 = (75/64)×48 = 225/4 = 56 1/4
5/8 of 48 is equal to 8/15 of 56 1/4
Answer:
x≤3
Step-by-step explanation:
<em>Step one- This equation has 23 greater than or equal to sign. Which means It can be at most 23</em>
<em>Step two- Find out what times 3x+14=23 In this case the answer is 3.3 Is the biggest number that can be multiplied by 3, +14 to get to 23.</em>
<em>Step three- Rewrite the Answer. Since we know that 3 is the highest numebr possible, we rewrite it to this equation</em>
<h3>x≤3</h3><h3>HOPE THIS HELPS :)</h3>
P² - r²
subtitute p =10 and r= -4
10² - (-4)² = 100 - 16 = 84
