In Triangle A B C, what is the value of x? Triangle A B C. Angle A is 112 degrees. Exterior angle to angle B is 2 x degrees and

Stolb23 [73]

Answer:

70°

Step-by-step explanation:

∠A =112°,

Exterior angle to angle B is 2x, therefore ∠B = 180 -2x (angle on straight line)

Exterior angle to angle C is 2x + 12, therefore ∠C = 180 -(2x +12) (angle on straight line) = 180 - 12 -2x = 168 - 2x

∠A + ∠B + ∠C = 180 (sum o angles in a triangle)

112 + 180 - 2x + 168 - 2x = 180

460 - 4x = 180

4x = 460 - 180 = 280

x = 280/4 = 70

x = 70°

What’s the slope of the graph? (photo included) giving out brainliest!

ludmilkaskok [199]

Answer:

Using the slope formula with points (0,-1) and (-4,4)

Step-by-step explanation:

Step 1: find the points, (0,-1) and (-4,4)

Step 2: Insert plot points into Slope formula: (tip: M means slope)

m(slope)= $\frac{y_{2} - y_{1}}{x_{2}-x_{1}}$ -> m(slope)= $\frac{4-(-1)}{-4-0}$

Step 3: Solve:

m(slope)= $\frac{5}{-4}$

Answer:

Slope is $\frac{5}{-4}$

or m = $\frac{5}{-4}$

OR (if your teacher wants the answer in decimal form rounded to the nearest 10th.) m = -1.3
