Answer:
B, ![\sqrt 156](https://tex.z-dn.net/?f=%5Csqrt%20156)
Step-by-step explanation:
B ![\sqrt156 = 12.489996](https://tex.z-dn.net/?f=%5Csqrt156%20%3D%2012.489996)
A![\sqrt144=12](https://tex.z-dn.net/?f=%5Csqrt144%3D12)
C![\sqrt169=13](https://tex.z-dn.net/?f=%5Csqrt169%3D13)
D![\sqrt196=14](https://tex.z-dn.net/?f=%5Csqrt196%3D14)
Answer:
x = ![\sqrt{65}](https://tex.z-dn.net/?f=%5Csqrt%7B65%7D)
Step-by-step explanation:
The altitude of the triangle must equal 4 because it is a right triangle with another leg of 3 and a hypotenuse of 5 (reason is due to the pythagorean theorem)
Therefore, the triangle on the right has legs of 4 and 7 and, again, use the phythagorean theorem to find 'x' (the hypotenuse)
+
= ![x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D)
16 + 49 = ![x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D)
65 = ![x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D)
x = sq rt 65
You idiot you answered your own question!
$34.80 because, if you add 15+2+21=58x12.00=696x0.05=34.80
Do sin(90)*13/15 which gives you 0.87 then do inverse of sin-1(0.87) which angle A = 60.45 degrees
