Answer:

B. 31°, 106°, and 43°.

Step-by-step explanation:

the sum of the measures of the angles in a triangle add up to 180°, so:

3x+1+11x-4+5x-7=180

19x-10=180

19x=190

x=10

now that we know x is equal to 10, we can find the three angle measures:

3x+1 -> 3(10)+1 = 31°

11x-4 -> 11(10)-4 = 110-4 = 106°

5x-7 -> 5(10)-7 = 50-7 = 43°

so, the answer is B.

Find BC if B(8,-7) and C1-4,-2).

Alika [10]

Using distance formula :

$\sqrt{(x_2 - x_1) {}^{2} + (y_2 - y_1) {}^{2} }$

$\sqrt{(8 - ( - 4)) {}^{2} + ( - 7 - ( - 2)) {}^{2} }$

$\sqrt{(12) {}^{2} + ( - 5) {}^{2} }$

$\sqrt{144 + 25}$

$\sqrt{169}$

Zinaida [17]

Answer:

x = 6

y = -4

Step-by-step explanation:

Plug y into the first equation.

5x - 7(-x+2) = 58

Then, solve for x.

Plug in x back to any one of the equations to find y.
