14-3^2 x (-2)
=14-9 x (-2)
=14- (-18)
=32
The correct statement which is true about angle 3 and 5 is, they are supplementary.
Step-by-step explanation:
- Two parallel lines are intersected by a third line so that angles 1 and 5 are congruent as they are supplementary.
- Supplementary Angles are Supplementary when the two angles are add up to 180 degrees.
- Examples of supplementary angles are 60° and 120°.
- Two lines are parallel when their slopes are equal. In order to see if the two lines are parallel, we must compare their slopes.
- A transversal is also known as a line segment, that intersects two or more other lines or also a line segments. When a transversal intersects parallel lines many angles are formed, which are known as congruent.
- If two parallel lines are intersected by a transversal, the corresponding angles are congruent.
- If two lines are intersected by a transversal, the corresponding angles are called as congruent i.e the lines are parallel.
Answer:
The need of help. I think that in some way, since Algebra can be quite difficult to understand students ask questions need help in order to understand more.
Step-by-step explanation:
as always, the sum of all angles in a triangle is always 180°.
therefore, the angle at B is
B = 180 - 27 - 90 = 63°.
for the missing sides we use the law of sine :
a/sin(A) = b/sin(B) = c/sin(C)
where the sides are always opposite of the related angles.
so,
AB/sin(90) = 12/sin(27)
since sin(90) = 1, we have
AB = 12/sin(27) = 26.43227118... ≈ 26.4
AC/sin(63) = 12/sin(27)
AC = 12×sin(63)/sin(27) = 23.55132607... ≈ 23.6
Answer:
72x + 288
Step-by-step explanation:
You would multiply 72 with (x + 4), which would leave you with 72x + 288. The value of x would be 72 i think
