4,8,12,16,20
Step-by-step explanation:
Answer:
x = 50°
Step-by-step explanation:
130 and x are adjacent angles on a straight line and sum to 180° , so
x + 130° = 180° ( subtract 130° from both sides )
x = 50°
Ok so if you divide that it will be a decimal
so it is 0.68
Answer:
5 is D
6 is C
Step-by-step explanation:
Define:
Equilateral - All sides and angles are congruent
Isosceles: Two congruent sides and two congruent angles
Scalene: No congruent sides or angles
Right triangle: A triangle with a right angle ( note that a right angle has a measure of 90 degrees )
obtuse triangle: A triangle with an obtuse angle ( obtuse angles have a measure of more than 90 degrees. )
Acute triangle : A triangle with an acute angle ( an acute angle has a measure of less than 90 degrees )
Answer:
the triangle shown in # 5 has a right angle and 2 congruent sides and angles
Therefore the triangle in #5 is a right isosceles
The triangle shown in #6 has an angle with a measure that is more than 90 degrees and have no congruent sides or angles therefore the triangle in #6 is an obtuse scalene.
Answer:
2x
Step-by-step explanation:
Solve the equation for a as follows:
First multiply both sides by 2a:
and then divide both sides by 2x:
