What are the answers to part A and part B?

Mathematics
1 answer:
Sophie [7]3 years ago
3 0

Answer:

Step-by-step explanation:

a. Sum of angles in a triangle is 180°

:- w° + 67° + <Y = 180°

<Y = 180° - 67° - w°

<Y = 113° + w°

b. Sum of angles in a triangle is 180°

:- <I + <K + <Y = 180°

33° + 67° + 14d - 19° = 180°

14d = (180- 33- 67 + 19)°

14d = 99°

d = 99/14

d = 7.1°

andrew-mc [135]

Answer:

2/3

Step-by-step explanation:

Convert the fractions to decimals.

2/3 = 0.666

4/5 = 0.8

14/18 = 0.777

34/50 = 0.68

From the decimals, 0.666 is the only option which falls between 0.5 and 0.75.
