Question

What’s the value of x in a triangle x top right 45 top left 98 bottom

Answer 1

Answer:

The value of x is 37°.

Step-by-step explanation:

Given that the total angles in a triangle is 180°. In order to find the x value, you have to substract 98° and 45° from 180° :

$x + 98 + 45 = 180$

$x = 180 - 98 - 45$

$x = 37$

Answer 2

Answer: 37

Step-by-step explanation:

If you add in all numbers inside the triangle, it should be equal to 180 degrees meaning x + 98 + 45 = 180.

To solve the unknown, we must first add in the numbers:

x + 143 = 180

To get the variable by itself, we must subtract 143 to both sides which gives us 37 degrees.

Now that we know that x is equal to 37, we should make sure it is the right answer, to do that, we need to replace x with 37:

37 + 98 + 45 = 180

By adding in all the numbers, we should get 180.
