Answer:
Step-by-step explanation:
sin(195º)= -√6+√2/4
cos(195º)=-√6-√2/4
tan(195º)=2-√3
Answer:
(x - 3)(x + 7)
Step-by-step explanation:
x^2 + 4x - 21
=> x^2 + 7x - 3x - 21
=> x(x + 7) -3(x + 7)
=> (x + 7)(x - 3)
Answer:
A
Step-by-step explanation:
theare are 5 part from 0 to -1
since, the value from 0 to -1 is -1 then if we break it to 5 part, each part has value of -1/5
so, to be -4/5, -1/5 must be multiplied by 4, so we need to go to the 4th part from 0, so it A
Step-by-step explanation:
ok so as u know the angles of a triangle add up to 180.
So we will be using that for help.
S+R+T=180
12x+13x+12x-4+2-3=180
37x-5=180
37x=185
x=5
Now we will plug in the value for x to find each angle
S= 13(5)-4
=61
T=12(5)-3
=57
R=12(5)+2
=62
Hope this helped:)
