Please help ive posted this question so many times and nobody helps :(

m<1 = 60

m<2 = 39

m<3 = 21

m<4 = 39

m<5 = 21

Step-by-step explanation:

this should be right so:

since bottom triangle is isoceles, then angles 3 and five should be equal. Since a triangle equals 180 degrees then, 180 - 138 = 42 which equal <3 +<5. 42 / 2 equals the measure for angle 3 = 21. angle 5 also equals 21.

now the top triangle is equilateral so all angles are equal (60 degrees). angle one is sixty. m<2 = 60 - m<3 which is 60 - 21 which is 39. both angle 2 and 4 are 39 degrees.

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:
