Question

Please help i need the answer done step by step

Answer 1

40 is the asnwer

Explanation:

1. Well, first of all we know that all right angles add up to 180 degrees. The degrees shown in the picture are 50, and 90. You can’t see the 90 exactly, but you can tell by that little square, that’s how it shows us!

2. Second step, we add up 60 and 90 which is 140. We got that, now we can subtract this 140 to the 180 to get our answer!

3. 180 – 140 is equal to 40!

4. Therefore, the 3rd angle is 40!

5. Not confident with my ansawer? Proof time!

6. 40 + 50 + 90 = 180

7. Since this all adds up to 180, it is true!

Have a great day!

Answer 2

x = 40

Explanation:

So a triangle is 180 degrees

and thats a right triangle = 90 degrees

you have three corners: 90, 50 & x

90 + 50 + x = 180

140 + x = 180

subtract 140 from both sides

x = 40
