Determine the measures of the angles marked with letters

1) Now,

a + 27° = 90° (right angle triangle)

◆ a = 63°

2) Now,

b + b + b = 90° (right angle triangle)

or, 3b = 90°

◆b = 30°

3) Now,

c + c + 40° = 90° (right angle triangle)

or, 2c = 90° - 40°

or, c = 50°/2

◆ c = 25°

4) Here,

◆ e = 41° (vertically opposite angle)

◆ f = 82° ( vertically opposite angle)

Now,

d + e + f = 180° (straight angle)

or, d + 41° + 82° = 180°

or, d = 180° - 123°

◆ d = 57°

Then,

◆ g = d = 57° (vertically opposite angle)

It is all correct answer...

I hope u understand...

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
