26/Sin(29) =28/Sin(C) ..... cross multiply..... 28sin(29) =26Sin(C) ..... 13.57=26Sin(C)..... divide 26.... .522=sin(C) .... sin^-(.522) .... Sin(C)=
31.47
Assuming that there is supposed to be a + sign in front of the 2 and 4; the answer is as follows.
3(x+2)+4(x-5)=10
3x+6+4x-20=10
7x-16=10
7x=16
x=2 2/7
Hope this helps :)
Let r be the lesser root and r^2 be the greater.......the sum of the roots = -b/a = -[-6] / 1 = 6
So we have that
r^2 + r = 6 → r^2 + r - 6 = 0
Factor
(r + 3) (r - 2) = 0
So r = -3 or r = 2
Then r^2 = 9 or r^2 =4
And the product of the roots = c/a = k/a = k
So....k = (-3)(9) = -27 or k = (2)(4) = 8
Check
x^2 - 6x - 27 = 0 factors as (x + 3)(x - 9) = 0 and the roots are -3 and 9
x^2 - 6x + 8 = 0 factors as (x -2) (x - 4) =0 and the roots are 2 and 4
Answer:
A
Step-by-step explanation:
Vertical angles are angles that are formed by 2 lines and are directly accross from each other. They do not share a ray, however they are always the same number of degrees.
so then the answer would be A, ∠ERT and ∠MRC since they are directly across from each other.
