Answer:
< FAD and <DAH make 90 degrees so they are complementary
<EAC and CAH make a straight line so they are supplementary
Step-by-step explanation:
Complementary angles add to 90 degrees
< FAD and <DAH make 90 degrees so they are complementary
Supplementary angles add to 180 degrees ( a straight line)
<EAC and CAH make a straight line so they are supplementary
First a reciprocal is a fraction but flipped over. So so if we have x/y, it's recipricam is y/x.
this helps to know when you understand that dividing by a fraction is the same thing as multiplying by that fractions reciprocal.
So ifnwenhave b/c and divide it by x/y we can also say b/c multiplied by y/x. it isnthensame thing.
now to use this for your problem.
5/31 divided by 15/23
or
5/31 times 23/15
all we have to do is multiple the 2 numerator and denominator and get:
115/465
now to reduce. divide both by 5 first
23/91
both numbers are prime so that would be answer
33.
We have an isosceles triangle, which means that two of the sides of the triangle are equals, the same is with the angles
side LM= side MN
angle L =angle N
Also we need to remember that the sum of the interior angles of a triangles is 180°
angle M=120
angle N=x
angle L=x
120+x+x=180
2x=180-120
2x=60
x=60/2
x=30
m < M =120°
m< N=30°
