Answer:
Step-by-step explanation:
( Being vertically opposite angles)
Vertically opposite angles are always equal.
Move variable to L.H.S and change it's sign
Similarly, Move constant to R.H.S and change it's sign
⇒
Collect like terms
⇒
Subtract 18 from 50
⇒
Divide both sides of the equation by 2
⇒
Calculate
⇒
The value of x is 16
Now, let's find value of m<AFD :
( sum of angle in straight line )
plug the value of x
⇒
Multiply the numbers
⇒
Add the numbers
⇒
Move constant to R.H.S and change it's sign
⇒
Subtract 98 from 180
⇒
Value of m<AFD = 82

Answer:
Step-by-step explanation:
Sum of angles in a Δ= 180°
x + 2x +3x = 180
6x= 180
Divide both sides by 6
x=30
sooo x= 1×30= 30, 2x= 2×30= 60, 3x=3×30= 90
since 30+60+90= 180
∴the angles are 30°,60° and 90° respectively
No, 2 x 7 is 14 which is even.
