Answer:

Step-by-step explanation:

Because the base is a straight line, each of the unknown angles in the triangle are 180 - 2h. This means that 360 - 4h + 40 = 180, so 400 - 4h = 180.

Now subtract -4h + 180 from both sides to get 220 = 4h so h = 55.

What's the x-intercept for number 26?

Lunna [17]

It gives function: h = -16t^2 + 40
water is when height is 0 so solve for 0= -16t^2 + 40
subtract 40 from both sides: -40 = -16t^2
divide by -16: -40/-16 = t^2
simplify: 5/2 = t^2
square root both sides: 1.58 = t
