Answer:
Find the value of X in triangles by subtracting known angle measurements from 180 degrees. Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle. If you are working with equilateral triangles, divide 180 by three to find the value of X. All of the angles of an equilateral triangle are equal.
Answer:
x = 50°
2x = 100°
Step-by-step explanation:
Chords AB and DC are equidistant (3 units) from the center E of the circle.
Since, the chords equidistant from the center of the circle are congruent.
Congruent chords intercepts congruent arcs.
Hence, x = 50°
2x = 2*50° = 100°
(a) If AB = CD and AB || CD then ABCD is a parallelogram.
(b) If AB ≠ BC then ABCD is not a rhombus.
First calculate the remaining angle in the triangle. which is going to be 180-65-75 = 40.
and basically the remaining angle should be the same as x. because of the (vertical opposite angle) theory.
therefore, x should be 40°
The least common denominator of two fraction is the least common multiple of the two denominator.
The least common multiple of 4 and 7 is their product 28, because 4 and 7 have no common factor.
Now, we need to manipulate both fractions so that they have denominator 28. Recalling that you can multiply numerator and denominator of a fraction by the same number without affecting its value, we have
So, the sum becomes
In fact, when two fractions have the same denominator, you can directly sum their numerators.
