A house uses an average of 10,000 kWh of energy per year. The owner is thinking of installing she has been told that each house will generate around 850 kWh annually how many solar panels should she install to supply 25% of her energy needs.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet
