Answer:
(–1, 1)
(4, –2)
Step-by-step explanation:
Let
(x,y) ----> the coordinates of point C
Applying the Pythagoras Theorem

step 1
Find the possibles values of x

Simplify

Solve the quadratic equation

The values of x are
x=-1 and x=4
step 2
Find the possibles values of y

Simplify

Solve the quadratic equation

The values of y are
y=-2, y=1
therefore
The possibles coordinates of point C are
(-1,1),(4,-2)

Answer:
98
Step-by-step explanation:
There are 7 sides to this polygon. Forget all the lettering on the figure. Concentrate on the number of triangles you can count. There are 5 of them. Each one has 180 degrees. So the total number of degrees on the interior of the figure is
5 * 180 = 900
All you have to do is add up all the angles including the x and equate them to 900
x + 146 + 122 +142+ 140 + 110 + 142 = 900 Collect the terms on the left.
x + 802 = 900 Subtract 802 from both sides
x = 900 - 802
x = 98
Answer:
third option
Step-by-step explanation:
Given the arithmetic sequence
14, 24, 34, 44, 54, ....
with f(1) = 14 and common difference d = 24 - 14 = 10
The recursive function allows a term in the sequence to be found by adding d to the previous term, thus
f(n + 1) = f(n) + 10 where f(1) = 14
