Answer:
73°
Step-by-step explanation:
Given: BD=BE
∠DBE= 50°
∠EAC= 42°
DE//AC and AE=CD
Attach is the new drawn diagram with M point.
∵ we know BD=BE, ∴ ∠BDE=∠BED= x ( taking x as unknown angle)
Remember, sum of triangle= 180°
Now, ∠BDE+∠BDE+∠DBE= 180°
⇒
⇒
Subtracting both side by 50, then dividing both side by 2
∴ °
We know, ∠MAC= ∠MCA= 42° (∵AM=MC)
Next, ∠EDC=DCA= 42° ( ∵ Alternate interior angle as we know DE//AC )
Now, we have ∠EDC= 42°, ∠BDE= 65°
∴ ° (∵sum of straight line= 180°)
⇒ °
⇒°
Subtracting both side by 107
∴∠ADC= °
∴∠ADC= 73°
<em><u>Solution:</u></em>
Given that, we have to find the greatest common factor of
The greatest number that is a factor of two (or more) other numbers.
When we find all the factors of two or more numbers, and some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor
First find the GCF of numbers and then find the GCF of variables and then multiply them together
<em><u>Step 1: GCF of 44, 22 and 11</u></em>
The factors of 11 are: 1, 11
The factors of 22 are: 1, 2, 11, 22
The factors of 44 are: 1, 2, 4, 11, 22, 44
11 is the greatest factor that is common in above three list
Then the greatest common factor is 11
Thus the greatest common factor is
Step 3: Multiply the GCF of 44, 22, 11 and GCF of
Thus
