In degree measure, the angles pi/3,pi/4 , and pi/2 are respectively: A. 60, 45, 90 B. 30, 45, 90 C. 45, 60, 90 D. 60, 30, 90 (al
aev [14]
<span>Solution :-
The value of pi expressed in radians and its equivalent degree is = 180 degree
Hence, the value of pi/3 = 180/ 3 = 60 deg
similarly, the value of pi/3 = 180/4= 45 deg
similarly, the value of pi/2= 180/2= 90 deg
Ans :-
The angles of pi/3, pi/4, pi/ 4 is = 60, 45, 90 degree respectively. Hence the right option is answer is A.</span>
10) The GCF of a set of numbers is the largest number that divides into both numbers.
The GCF of 24 and 36 is 12.
15)
can be simplified by dividing the top (numerator) and the bottom (denominator) by the GCF. The GCF of 30 and 54 is 6. The new fraction is
. 6/9
20) The GCF of
is 11. The new fraction is
. 5/8

Step-by-step explanation:
The given figure is an isosceles trapezoid, this means that the two non-parallel sides in the trapezoid are congruent. One of the properties of an isosceles triangle is that opposite angles are supplementary. This means that the sum of angles opposite each other in an isosceles trapezoid is (180) degrees. One can apply this here by stating the following,
