Answer:
tan x = 5/12
Step-by-step explanation:
given:
- sin x = 5/13
- cos x = 12/13
to find
- tan x
solving
tan x = sin x / cos x
tan x = (5 / 13) / (12 / 13)
tan x = 5 / 12
You put the line in the middle of all the points. Example above
Answer:
inches and feet
Step-by-step explanation:
because we arent like all the other countries tha tuse kilograms and kilometers and stuff like that.
Answer is 75
Total angles of a triangle = 180
Third angle =180 - 67 - 38= 75
Best Answer: Look at the discriminant of the quadratic equations to find the number and type of solutions. The discriminant is part of the quadratic formula underneath the square root sign: b^2 - 4ac. If it is positive, then there are two real solutions for that quadratic equation. If the discriminant is 0, then there is one real solution. If the discriminant is positive, then there are two imaginary solutions.
1.) x^2 - 18 = 0
a = 1, b = 0, c = -18
b^2 - 4ac
(0)^2 - 4(1)(-18)
72
ANSWER: 2 real solutions
2.) x^2 + 5x + 7 = 0
a = 1, b = 5, c = 7
b^2 - 4ac
(5)^2 - 4(1)(7)
25 - 28
-3
ANSWER: 0 real solutions
Hope this helps
