Answer:
x=4
Step-by-step explanation:
12=4-4x
4-4x=12
Add 4 to both sides
4x=16
Divide by 4
x=4
Answer:
perimeter

i can just tell but it help if you put a picture
Answer:
triangle cannot be right-angled and obtuse angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute. Therefore, an obtuse-angled triangle can never have a right angle; and vice versa. The side opposite the obtuse angle in the triangle is the longest.
Step-by-step explanation:
No; in a right triangle, the other two angles are complementary so they are both less than 90° CLASSIFYING TRIANGLES Copy the triangle and measure its angles.
Answer:
139°
Step-by-step explanation:
Corresponding angles theorem:
When a transversal line intersects two parallel lines, the angles formed from the intersection are congruent in pairs. For example with your problem, using the Corresponding Angles Theorem (one of the few theorems/postulates used to find angles on transversals), the angles are paired on the same place on the first parallel line as they are on the second. Since the corresponding pair of (<em>x</em>)° is given, the angle of <em>x</em> is given. (<em>x</em>)° = 139°
