Question

Answer these Please

Answer 1

1b) 70, 40
1c) 45, 90
1d) 25%
1e) 5%
2a) 360
2b) 180
2c) protractor
2d) compass
2e) diameter
2f) radius
2g) 90
2h) acute

For 1b), the other equal angle would be 70; the remaining angle would be 180-(70+70) = 180-140 = 40.
For 1c), the other equal angle would be 45; the remaining angle would be 180-(45+45) = 180-90 = 90.
For 1d), he saved 50/200; dividing this, we get 0.25; 0.25*100 = 25%.
For 1e), he saved 28/560; dividing this, we get 0.05; 0.05*100 = 5%.
