NEED DONE ASAP!!
almond37 [142]

Answer:

A. 3x^2 + 4 = 52

     3x^2 = 52 - 4

     3x^2 = 48

       x^2 = 48/3

       x^2 = 16

        x    = \sqrt{16}

        x = 4

B. x^2 - 121 = 0

     x^2  = 121

       x = \sqrt{121}

       x = 11

C. (b + 4 )2 = 49

    2b + 8 = 49

    2b  = 49 - 8

     2b = 41

        b = 41/2

What is m∠D? Enter your answer in the box.
Alex73 [517]

Answer:

D = 32

Step-by-step explanation:

A+ B + E = 180 since they form a triangle

14+ 45 + E = 180

E = 180 -14-45

E =121

E on either triangle is the same since they are vertical angles

C+D+E = 180 since they form a triangle

27+ D + 121 = 180

D = 180-121-27

D =32
