There is 180 degrees in a triangle. What you need to do is set up an equation and solve for x.

(7x + 10)+(x+20)+2x =180

Combine like terms:

10x + 30 = 180

Solve for x:

10x= 150; the largest angle

X=15

Plug x into the equations

7(15)+10= 115

(15) + 20 = 35

2(15)=30

Just to check your work:

115+30+35=180

liraira [26]

A would be the correct answer because he is up in elevation so that makes the 1200 positive and he goes down 20.4 which is negative and is goes that far down!!

hope this helps

Wich set of angles measure could be the measure of the interior angles of a triangle? 90,42 and 58. 60,60 and 60. 100,48 and 43.
4vir4ik [10]

Answer:

60°,60° and 60°.

Step-by-step explanation:

The sum of the interior angle of a triangle

=180°

So, let us test measured sets to get which of them could be the interior angles of a triangle.

The sum of the first measured set

= 90° + 42° + 58°

=190°

Also, the sum of the second measured set

= 60°+ 60° + 60°

=180°

The sum of the third measured set,

= 100°+ 48° + 43°

=191°

Finally, the sum of the fourth measured set

= 31° + 75°+ 70°

=176°

We can clearly conclude that, the measured set 60°,60°and 60° could only be the the set of interior angles of a triangle. Since it is the only set that add up to 180°

Mademuasel [1]

Answer:

1. 5

2. 12

3. a. 12

3. b. 18

Step-by-step explanation:

1. 50 - 45 = 5.

2. 26 - 18 = 8. 30 - 18 = 12. 12 + 8 = 20. 20 + 18 = 38. 50 - 38 = 12.

3. a. 24 - 12 = 12.

4. 40 - 12 = 28. 24 - 12 = 12. 28 + 12 + 12 = 52. 70 - 52 = 18.
