Answer:
The side C equals to 10. hence the answer is letter A
Step-by-step explanation:
To solve this, we need to use trigonometric functions.
we know that sin (α) = Lo / H for a triangle. Being Lo : Length of the opposite side and H: Length of the hypotenuse.
Given α= 45º and Lo= 5√2 and replacing in the equation:
sin (45º) = 5√2 / C (1)
Using trigonometric identities we know that sin(45º) =(√2)/2. Replacing in equation (1):
sin (45º) = (√2)/2 = 5√2 / C ⇒ C = 2 *5 *√2 / (√2) ⇒ C=10
Answer:
Step-by-step explanation:
Its parallel so they are equal
7x-40=5x+10
2x=50
x=25
Answer:
(x, y) = (-15, -14)
Step-by-step explanation:
y = x+1
y = 2/3x - 4
Next, we will substitute the value of y (first equation) into the second equation.
x+1 = 2/3x - 4
1/3x + 1 = -4
1/3x = -5
x = -15
So, y = -14
