Answer:

90 degrees

Step-by-step explanation:

Calculate whether an angle is 90 degrees using the Pythagorean Theorem. This well-known theorem is often phrased as "A squared plus B squared equals C squared," which indicates that the sum of the squares of lengths of the adjacent sides of a right triangle is equal to the square of the length of the hypotenuse side.

parallelogram

1. perimeter 10(2)+10(2)=32+20

perimeter = 52cm

area=b times h

area = 16(9)=144cm2

2 TRAPEZOID

perimeter =( 21+24+25+44.67)m

=114.67m

area= 1/2( b1+b2)h

1/2(44.67+25)20

696.7m2

3. perimeter = 2+3+12+2+3+5+3+2+9+7+3

=51cm

area = 54+6+6+6=72cm2

4. perimeter is 10+4+2+3+ 2+4+10+23 = 58cm

area is 

(11+23).8=37.8

=272

Write the equation of the line that passes through (−2, 6) and (2, 14) in slope-intercept form. (2 points)

melisa1 [442]

Answer:

$y = 4x + 14$

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation we must first find the slope of the line

Slope of the line using points (−2, 6) and (2, 14) is

$m = \frac{14 - 6}{2 + 2} = \frac{8}{2} = 4$

Now we use the slope and any of the points to find the equation of the line.

Equation of the line using point ( - 2, 6) and slope 4 is

$y - 6 = 4(x + 2) \\ y - 6 = 4x + 8 \\ y = 4x + 8 + 6$

We have the final answer as

$y = 4x + 14$

Hope this helps you
