I need to solve for x
podryga [215]

Answer:

30 degrees

Step-by-step explanation:

This is an isosceles triangle having 2 equal sides and 2 equal base angles.

since the measurement of all the internal angles of the triangle is 180 degrees and we know that each base angle is 75 degrees

solving for x:

75 + 75 + x = 180 degrees

150 + x = 180

x = 180 - 150

x = 30 degrees

A rock is thrown into the air. The height of the rock is modeled by s(t) = −16tଶ + 64t + 80 feet for t ≥ 0 seconds. The rock hit
ExtremeBDS [4]

Answer:

144 feets

Step-by-step explanation:

Look on s(t) like quadratic function. We need to find maximum of the function using 1st diferetioal:

s(t)=-16t^2+64t+80

s’(t)=-32t+64

S’(t)=0 if t=2

For t>2, s’(t)<0

For t<2, s’(t)>0. So the maximum od function is in the point 2.

S(2)=-16*4+64*2+80=-64+128+80=144
