The product is equal zero if one of the factors is equal zero.Therefore:
Answer:
x = 22
y = 35
Step-by-step explanation:
Because its an isosceles triangle, you know the base angles are equal so:
Solving:
subtract 2x from both sides
add 11 to both sides
Next, find the angle measures of the two base angles:
To find y, you know that the interior angles of the whole triangle add up to 180, so you have
solving,
subtract 110 from both sides
divide both sides by 2
so.... there, using the slope's rise/run values, you can get the subsequent point, and to graph a LINEar equation, since it's just a LINE, all you need is two points, graph those two, run a line through them, that's the graph of the line.
Step-by-step explanation:

Therefore, the eqaution is y = 2x-5.
Alternative:
<u>Steps</u><u>:</u>
- Find slope using slope formula and use one point formula.
- Simplify in the form of y = mx+c form.
Formula:
- Slope = (y2-y1)/(x2-x1)
- One point formula= (y-y1)= m(x-x1)
The points are; (1,-3) and (3,1).
Now;
Slope= (1- (-3))/(3-1)
= (1+3)/2
= 2
Again;
Using one-point formula.
(y+3) = 2(x-1)
y+3= 2x-2
y = 2x -5
Therefore, the equation is y = 2x-5.

Answer:
Step-by-step explanation:
Given that:
and
To find:
Solution:
First of all,we have cos value as negative and tan value as positive.
It is possible in the 3rd quadrant only.
will lie in the 2nd quadrant so will be negative again.
Because Cosine is positive in 1st and 4th quadrant.
Formula:
Here
But as we have discussed, will be negative.
So, answer is:
