Answer:
![49.5 , -0.5](https://tex.z-dn.net/?f=49.5%20%2C%20-0.5)
Step-by-step explanation:
![a + b =49\\a - b = 0.5\\a= 49.5\\b= -0.5](https://tex.z-dn.net/?f=a%20%20%2B%20b%20%3D49%5C%5Ca%20-%20%20b%20%3D%200.5%5C%5Ca%3D%2049.5%5C%5Cb%3D%20-0.5)
Answer:
The answer is 5.
Step-by-step explanation:
(2x+3)(x+1) Use the FOIL METHOD
2x²+2x+3x+3
2x²+5x+3.
Gcf first
21y(y+5)
solutions are 0,-5
To solve this we use trigonometric functions that would relate the hypotenuse y and the given values. For this case we use cosine function which is expressed as:
cosine theta = adjacent side / hypotenuse
cosine 52 = 35 / y
y = 35 / cos 52
y = 56.85
