Z= 60 degrees is the answer
kirza4 [7]3 years ago
4 0

Answer:

Z = 60°

Step-by-step explanation:

Since, given triangles are similar. Corresponding angles of similar triangles are congruent.

Therefore,

Z = 180° - (65° + 55°)

Z = 180° - 120°

Z = 60°

Write an equation of the perpendicular bisector of the segment with the endpoints (8,10) and ( -4,2).
ale4655 [162]

Answer:

The required equation is:

y = -\frac{3}{2}x+9

Step-by-step explanation:

To find the equation of a line, the slope and y-intercept is required.

The slope can be found by finding the slope of given line segment. A the perpendicular bisector of a line is perpendicular to the given line, the product of their slopes will be -1 and it will pass through the mid-point of given line segment.

Given points are:

(x_1,y_1) = (8,10)\\(x_2,y_2) = (-4,2)

We will find the slope of given line segment first

m = \frac{y_2-y_1}{x_2-x_1}\\= \frac{2-10}{-4-8}\\=\frac{-8}{-12}\\=\frac{2}{3}

Let m_1 be the slope of perpendicular bisector then,

m.m_1 = -1\\\frac{2}{3}.m_1 = -1\\m_1 = \frac{-3}{2}

Now the mid-point

(x,y) = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})\\= (\frac{8-4}{2} , \frac{10+2}{2})\\=(\frac{4}{2}, \frac{12}{2})\\=(2,6)

We have to find equation of a line with slope -3/2 passing through (2,6)

The equation of line in slope-intercept form is given by:

y = m_1x+b

Putting the value of slope

y= -\frac{3}{2}x+b

Putting the point (2,6) to find the y-intercept

6 = -\frac{3}{2}(2)+b\\6 = -3+b\\b = 6+3 =9

The equation is:

y = -\frac{3}{2}x+9

I have to solve for ABC n round to nearest whole number​
Brums [2.3K]

Answer:

∠B

7(13)-1=90˚

Step-by-step explanation:

Are you saying ∠ABC or ABC as sides?

1. ∠ABC

(7x-1)+(4x+1)+(3x-2)=180˚

14x-2=180˚

14x=182

x=182/14

x=13˚

2. plug in

∠A

4(13)+1=53˚

∠B

7(13)-1=90˚

∠C

3(13)-2=37˚
