Please help me with this question by using completing the square (alg 2). The answer should be (2, -6)

Lorico [155]

Answer:

(2, -6)

Step-by-step explanation:

5n^2+20n-60

(5n+30)(n-2)

5n + 30 = 0

5n = -30

(5n = -30)/5

n = - 6

n - 2 = 0

n = 2

answer: (2, -6)

Triangle FGH has the following measures: m∠G=47∘, f=30.2, and m∠H=79∘. What is the length of side g? 31.5 36.6 54.0 27.3

Ghella [55]

Answer:

27.3

Step-by-step explanation:

47 + 79 = 126

180 - 126 = 54

m∠F= 54∘

then use the sine rule

looks like if you were solving a ratio problem

30.2/sin of 54∘ = g/sine of 47∘

30.2/.809 = g/.7314

.809g = 30.2 times .7314

.809g = 22.08828

g = 22.08828/.809 =
