Answer:
x=3
Step-by-step explanation:
Since all the angles are equal, this is an equilateral triangle. This means that all sides are equal
BC = AC
5x = 3x+6
Subtract 3x from each side
5x-3x =3x-3x+6
2x=6
Divide by 2
2x/2 =6/2
x=3
-11 - -3 = -8 hope that helps!!
Answer:
BC ≈ 3.3
Step-by-step explanation:
Using the tangent ratio in the right triangle.
tan A =
, that is
tan20° =
=
( multiply both sides by 9 )
9 × tan20° = BC , then
BC ≈ 3.3 ( to the nearest tenth )
Step-by-step explanation:
C. A =3 , B = 5
6y + 15 = 3 ( 2y + 5 )
A = 3
B = 5
