Answer:

  (d)  h = 2A/b

Step-by-step explanation:

Multiply both sides of the equation by the inverse of the coefficient of h.

  A = \dfrac{1}{2}bh=\dfrac{b}{2}\cdot h\\\\\dfrac{2}{b}\cdot A=h\\\\\boxed{h=\dfrac{2A}{b}}

BRAINLIEST ANSWER!! please help
DiKsa [7]

Answer:

k=45

Step-by-step explanation:

Since the sum of the measures are 180 and the measures are 45 degrees, k degrees, and 2k degrees, we can conclude that 45+2k+k=180. 2k and k are like terms, so you can add 2k and k to get 3k.Then, you would have  45+3k=180. Since you are finding k, you want to isolate k as best you can. To do this, you subtract 45 on both sides 45-45+3k=180 -45 \\3k=135 as shown by the equation, 180-45 is 135. Then, you divide 3 on both sides to get k=45.
