Question

Find the value of x ​

Answer 1

x = 25°

Explanation:

<BDC + BCD = <ABD I know that part may seem confusing but Im just giving you a little boost of knowledge about it. So later on in math ( I imagine that your barely starting off with this stuff) it will become more complex. You have to lable the sides because later on you will have to find the decimales or whole numbers in meters inches or whatever. But yea you dont need to worry abbout that till later. :)

x + 90° =115°

Answer 2

x = 25

Explanation:

• 115° is the measure of the exterior angle of the given right ∆.

• Thus, by exterior angle theorem of a triangle, we have:

• x° + 90° = 115°

• -> x° = 115° - 90°

• -> x° = 25°

• -> x = 25
