Find the angle measure

Let the missing angle which we need to find be x

In the First triangle the two angles are 45° and 60°

Thus the third angle is

: 180° - (60+45)

= 180 - 105

= 75°

Now 75° + 70° = sum of opposite angles of the tangle

=> 145 = x + 40

hard to find the answer

Step-by-step explanation:

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1
