Answer:
13, 16, 23
Step-by-step explanation:
The first side is x.
The second side is x + 3
The third side is 2x - 3
(x) + (x +3) + (2x - 3) = 4x
4x = 52
x = 13
Answer: i think it’s distributive don’t kill me if it’s wrong
Step-by-step explanation:
2x-7y=0
2x=7y
x=7/2y
Substitute that into x-6y=-5
7/2y-6y=-5
-2.5y=-5
y=2
x=7/2 x 2 = 7
x=7, y=2
Hope this helps.
Answer:
sin=0
cos=-1
tan=0
csc=undefined
sec=-1
cot=undefined
Step-by-step explanation:
On the unit circle, . The sin of theta is therefore 0, the cosine is -1, and the tangent is 0/-1=0. Since the following functions are just the reciprocals of the previous ones, the cosecant is 1/0=undefined, the secant is 1/-1=-1, and the cotangent is 1/0= undefined. Hope this helps!
