Answer: B. 40

Step-by-step explanation: A triangle’s angles will always add up to 180 degrees. Add the 2 angles that are given. 90 + 50 = 140. Subtract this number from 180. 180 - 140 = 40. The third angle is 40 degrees.

Answer:

40°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 given angles from 180 for third angle

third angle = 180° - (90 + 50)° = 180° - 140° = 40°

Part A. Write an equation of a line that is perpendicular to the line y = 2/3x + 5 and passes through the point (4, 0).

fenix001 [56]

Answer:

$y = -\frac{3}{2}x+6$

Step-by-step explanation:

Given:

The given equation of the line $y = \frac{2}{3} x + 5$ that passes through the point (4, 0).

Part A.

The equation of the line.

$y=mx+c$ -----------(1)

Where:

m = Slope of the line

c = y-intercept

The given equation of the line.

$y = \frac{2}{3} x + 5$

Comparing the given equation with equation 1.

The slope of the line is $m=\frac{2}{3}$ and y-intercept $c = 5$

We know that the slope of the perpendicular line is $(-\frac{1}{m})$ .

So the slope of the perpendicular line is $(m=-\frac{1}{\frac{2}{3}}=-\frac{3}{2})$ .

Using point slope formula we write the equation of the perpendicular line that passes through the point (4, 0).

$y-y_{1} = m(x-x_{1}$

Now we substitute the slope of the perpendicular line $m=-\frac{3}{2}$ and $y_{1} = 0, x_{1}=4$ from point (4, 0) in above equation.

$y-0 = -\frac{3}{2}(x-4)$

$y = -\frac{3}{2}x-(-\frac{3}{2}\times 4)$

$y = -\frac{3}{2}x-(-3\times 2)$

$y = -\frac{3}{2}x-(-6)$

$y = -\frac{3}{2}x+6$

Therefore the perpendicular line equation is $y = -\frac{3}{2}x+6$ .

Part B.

1. The slope of the perpendicular line is $m=-\frac{3}{2}$ .

2. The y-intercept of the perpendicular line is 6.

3. The equation of the line $y = -\frac{3}{2}x+6$ is perpendicular to the equation of line $y = \frac{2}{3} x + 5$ .

GIVING BRAINLIEST! can anyone answer?

yaroslaw [1]

Answer:

1. A. contain a right angle

1. B. opposite sides are parallel

2. (c) 2 pairs of parallel sides

3. (b) 2 sides of equal length

Step-by-step explanation:

Here you are asked to find patterns and to make use of the definitions of different geometric figures.

The figures in Circle A do not all have the same number of sides, or sides of the same length. However, they do all have at least one right angle.

The figures in Circle B are rectangles and parallelograms. The attributes listed in question 2 can be used here. They all have two pairs of parallel sides.

As we observed in question 1, rectangles and parallelograms share the feature of 2 pairs of parallel sides.

A kite may have 2 pairs of equal-length sides. While a square and a rhombus have 4 sides of equal length, that description is not true of rectangles and parallelograms in general.

Angles in a rectangle are all 90°, while those in a parallelogram may not be. The offered descriptions of angles do not apply to apply to both shapes.

An isosceles triangle has two sides equal length and two equal angles. An equilateral triangle is a special case of an isosceles triangle in which all three sides are equal, as are all three angles. The description that applies to both kinds of triangles is 2 sides of equal length.
