Question

angle ABC=90° ,
(a) Find the angle CBD
(b) Find the supplement of angle of ABD
solve it by step by step​

Answer 1

Answer:

(a) 25, (b) 25

Step-by-step explanation:

The supplement angle of ABD is CBD.

(x-5) + (2x + 5) = 90

= (x + 2x) + (5-5) = 90

= 3x + 0 = 90

= 3x = 90

= x = 90/3

= x = 30

So, x - 5 = 25

Hope this helps you!

Answer 2

Answer:

since, angle ABC=90°

than angle ABD+angle DBC= 90°

( 2x +5)°+(x-5°)=90°

2x+5+x-5=90°

3x=90°

x=3/90°

x=30°

now angle ABD=2x+5

=2×30°+5

=65°
