Answer: angle 1=129 degrees
Step-by-step explanation:
180 - 99 - 30 = 51
all the angles of a triangle should add up to be 180 degrees
51+99+30=180
angle 1 is supplementary to the angle that is 51 degrees so it would be 129 degrees. 180-51=129
Tan 135 = -1
so rectangular coordinates are (-7 sqrt2, 7 sqrt2)
Answer:
G(x,y)=(-4,0)
Step-by-step explanation:
We use the section formula:
Given:
We substitute the values to get:
(5,0) if there is no y then it is a 0
If you need to solve this equation you can multiply the both side of equation on (-1). Like that
<span>2 = (-x);
-1·2 = (-1)·(-x)
if you multiply negative and </span><span>positive </span>you'll have negative,
if you multiply negative and <span>negative you'll have </span><span><span>positive. So
</span>
</span>-2 = x. or
x = -2.
The answer is -2.
