Calculate both numbers:
1+3=4
When multiplying a number by 11, you add both digits together and place it in between the numbers:
13x11=143
1. a=h(b+c)
2. distribute the h:
a=hb+hc
3. move the 'hb' to the left:
a - hb = hc
4. subtract the a from both sides:
-hb = hc - a
5. divide both sides by -h to isolate b:
b = -hc+a/h
Answer:
The correct option is A.
A) m, because ΔABC ~ ΔEDC
Step-by-step explanation:
Consider the both triangles.
<B = 60°
<D = 60°
<B and <D are congruent
<ACB = 90°
<DCE = 90°
<ACB and < DCE are also congruent.
As sum of the angles of triangle is 180°
<A = 180° - <ACB - <B
<A = 180° - 90° - 60
<A = 30° = m
<E = 180° - <DCE - <D
<E = 180° - 90° - 60°
<E = 30°
As m = 30°
<E = <CED = m
As segment AD cuts segment BE, which results in formation of two triangle, and as all angles of both triangles are equal, both triangles are similar.
