Question

in the following picture find the values of a and b ​

Answer 1

Answer:

b=55°

a=35°

Step-by-step explanation:

a:75-5=70,70÷2=35

b; 65-10=55°

Answer 2

Answer:

a = 5 degree ;

Step-by-step explanation:

here, it is given that angle1 = (2a+5) degree

angle2 = 75 degree

angle3 = 65 degree

angle4 = (b+10) degree

now , from the figure,

2a+5 + 75 = 90 degree (angle sum property) ----------(i)

2a+80 = 90

2a = 10

a = 5 degree

b + 10 = 65 degree (angle sum property) ----------(ii)

b = 55 degree

therefore a = 5 degree ;  b = 55 degree
