In triangle ABC, m<A = 8x +12, m<B = 5x+14, m<C = 2x +4. What is the m<A ? Need help....please

1 answer:

6 0

Triangle
m<A + m<B + m<C = 180
8x +12 + 5x+14 + <span>2x +4 = 180
15x + 30 = 180
15x = 180 -30
15x = 150
x = 10

m<A </span><span>= 8x +12
</span>m<A = 8(10) +12
m<A = 80 + 12
m<A = 92

answer
m<A = 92

What is the equation of the line that passes through the point (6,3) has a slope of -1/3

DerKrebs [107]

Answer:

y = -1/3x + 5

Step-by-step explanation:

y = mx + b

so y = 3, x = 6, m = -1/3

then 3 = (-1/3)6 + b

3 = -2 + b

b = 5

so y = -1/3x + 5

Answer:

n = - $\frac{4}{7}$

Step-by-step explanation:

Given

$\frac{2}{3}$ (1 + n) = - $\frac{1}{2}$ n

Multiply both sides by 6 ( the LCM of 3 and 2 ) to clear the fractions

4(1 + n) = - 3n ← distribute left side

4 + 4n = - 3n ( add 3n to both sides )

4 + 7n = 0 ( subtract 4 from both sides )

7n = - 4 ( divide both sides by 7 )

n = - $\frac{4}{7}$
