The measure of angle Y is 45°, and the measure of angle Z is 70°. A triangle has angles X, Y, Z. The exterior angle to angle X is W. What is the measure of angle W?

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post

Num of plants = (original#ofplants)*(1.6)^t

Iagree that is the answer to the question
