Aleksandr [31]2 years ago
6 0

a) The gradient of a line perpendicular to AB is -2.

b) equation of line is y=-2x+6

<h3>What is gradient?</h3>

The gradient is the measure of the steepness of a straight line.

a)The gradient of line is

=(-2-2)/(7+1)

=-4/8

=-1/2

So, gradient of a line perpendicular to AB is  -2

b)The coordinates of mid point (3, 0)

m = -2

So,

0= -6+ b

b= 6

So, equation of line is y=-2x+6

Solve for x and state the measure of the angles with an x in them
Arada [10]

Answer:

x = 83

Step-by-step explanation:

The sum of the angles of a quadrilateral is 360

75+x+97+105 = 360

Combine like terms

x+277=360

Subtract 277 from each side

x+277-277=360-277

x = 83

if 8 and 15 are two smallest values in a pythagorean triple, what is the largest value, c, in the triple
GaryK [48]

Answer:

c = 17

Step-by-step explanation:

Use the Pythagorean Theorem to solve this problem.

The equation is a² + b² = c².

"a" and "b" are the length of the two shorter sides or values.

"c" is the length of the longest side or value, also the hypotenuse.

Since we know the two smaller values, we can <u>replace "a" and "b" with 8 and 15</u>. It does not matter which letter you decide to replace with which number.

Then<u> simplify and  isolate "c" </u>to find the largest value.

a² + b² = c²

8² + 15² = c²         Substitute "a" and "b". Square the numbers to simplify

64 + 225 = c²        Add to simplify

289 = c²        

√289 = √c²        Square root both sides

√289 = c      "c" will be isolated because √ and ² are reverse operations

c = √289    Put 'c' on the left side for standard formatting.

c = 17           Answer

Therefore the largest value, c, is 17 in the triple.
