Question

2. Find m angle 1

73

88

60

80

Answer 1

88°

Explanation:

RULES:

1. angles on a straight line add up to 180 degrees
2. angles in a triangle add up to 180 degrees

so.

because of rule 1, we do 180-120 to get 60, to get that right corner angle. Now, we know 2 angles. So, (because of rule 2), we can do 60+32 = 92, and 180-92 = 88

So, 1 = 88

Hope this helps! If it doesn't make sense, feel free to ask me to explain it further.
