Question

Find m angle ABC I really need the answer to this

Answer 1

Step-by-step explanation:

As it is a right angle ,

2x + 14 + x + 7 = 90⁰

3x + 21 = 90⁰

3x = 69

x = 23

ABC = 23 + 7 = 30⁰

Answer 2

To find <ABC, the first thing you would need to do is to find angle DBA and the value of x

As <DBE is a right angle, <DBE is on the same straight line as well,meaning that it would be 90° , a right angle as well.

It also mean that the total sum of the angles unknown would be 90°

To find x,we need to set up an equation:
(2x+14)+ (x+7) = 90
3x+21 = 90
3x = 69
x = 23

Thus,<ABC would be
(23)+7
=30°

Hope it helps!
