Question

Calculate the unknown angles marked in Fig. 1, 2 and 3:​

Answer 1

Answer:

x= 52°

y= 70°

z= 47°

Step-by-step explanation:

We know that sum of all interior angles of a triangle= 180°

So in fig 1

x= 180-(90+38)= 180-128= 52°

in fig 2

y= 180-(80+30)= 180-110= 70°

in fig 3

z= 180-(90+43)= 180-133= 47°

mark me as brainliest please

Answer 2

Answer:

The Correct Answer is x = 52, y = 70, z = 47

Step-by-step explanation:

The total of a triangle's internal angles equals 180°, according to the angle sum property. The sum of the angles in every triangle, whether acute, obtuse, or right, will always be 180°. This can be expressed in the following way: A + B + C Equals 180° in an ABC triangle.

1) 90 + 38 + x = 180

   38 + x = 90

   x = 52

2) 80 + 30 + y = 180

   30 + y = 100

   y = 70

3) 90 + 43 + z = 180

   43 + z = 90

    z = 47
