Construct<span> a perpendicular from the </span>incenter<span> to one side of the triangle to locate the exact radius. 3. place compass point at the </span>incenter<span> and measure from the center to the point where the perpendicular crosses the side of the triangle</span>
(-5,-3) since plug in a=b-2 into the first equation and then solver for b. You get -3.-3-2=-5 which is a
A straight angle measures 180º.
A triangle's interior angles also measure 180º.
The angle measuring 130º is complementary to the corresponding interior angle, so that interior angle plus 130 has to equal exactly 180º.
180 - 130 = 50º
45 + 50 = 95º, so subtract that from 180 to find the measure of the last interior angle of the triangle.
180 - 95 = 85º
That angle of 85º is complementary to the other outside angle, n, and to find that subtract 85 from 180.
180 - 85 = 95º
n = 95
Hope this helps!
Answer:
x=-4
x=6
Step-by-step explanation:
Lets put to work the well known quadratic equation:
Let us also, remember the given equation: x^2-2x-24=0
Where 'a' would be equals to 1, 'b' equals to -2 and c equals to -24.
The quadratic equations with those values is:
Where we obtain two values.
x1= -4
and x2= 6
<span>-7(8 + k)
= -7(8) -7(k)
= -56 - 7k
= -7k - 56
answer
</span><span>2.-7k - 56</span>
