Length of each section is 15/6 = 2 1/2 feet
Its B
6:36 is what i would guess.
Lines 2 and four r perpendicular I think
Answer:
cos A = x.
Step-by-step explanation:
Because we have a right-angled triangle, m < A + m < C = 90 and sin C = Cos A.
So cos A = x.
The sum of all angles of a triangle is equal to 180°
On a isosceles triangle, the base angles are the same.
We add them together 56° + 56° = 112°
To know X, we subtract 112° from the total
180° - 112° = 68°
X = 68°
OR as an equation
56 + 56 + x = 180
112 + x = 180
x = 180 - 112
x = 68
