Question

Please help :(
Find the value of the indicated angles

Answer 1

Answer:

here is your answer

pls mark it as brainliest

so here we go

Step-by-step explanation:

now here angle containing (8b-1) and angle containing (6b+9) are equal because they both intercepts same angle on circumference of circle

so as angles inscribed in same arc are equal

8b-1=6b+9

ie 2b=10

so b=5

thus substitute it in missing values you get

(8×5)-1

=40-1

=39

and (6b+9)

=(6×5)+9

=30+9

=39

so thus option option b ie 39 degrees is ryt answer

Answer 2

Answer:

(8b -1)° = 39° & (6b+9)° = 39°

Step-by-step explanation:

GIVEN:

Two angles (8b -1)° and (6b+9)° are in the same arc.

TO FIND:

Measurements of the angles

SOLUTION:

We know that,

Angles inscribed in same arc in a circle are always equal.

A/Q

(8b - 1)° = (6b+9)°

=> 8b - 1 = 6b+9

=> 8b -6b = 9+1

=> 2b =10

=> b = 10/2

b = 5

Hence, first angle = (8b - 1)°

= (8×5 - 1)°

= (40 - 1)°

= 39°

Second angle = (6b+9)°

= (6×5+9)°

= (30+9)°

= 39°
