Answer:
X=140
Step-by-step explanation:
<em>Firstly, any Quadrilateral has a total sum of its angle equal to 360 degrees</em>
<em>The attachment you are showing us shows that we already know two angles</em>
<em>(70)&(60) degrees. I am assuming the line DC is a tangent, so angle ADC must be 90 degrees since a full angle on a tangent is equal to 180 degrees and there is 90 from the other side (180-90=90). Now we know 3 angles and what you have to do is find X so that when you add them all up they make a sum of 360. </em>

X+70+60+90=360
X=360-70-60-90
X=140
The sum of all the angles of the triangle is 180°.
80 + 3x + x = 180°
80 + 4x = 180°
4x = 180 - 80
4x = 100
x = 100/ 4
x= 25
Answer:
f(x) = 2(x + 4)² - 2
Step-by-step explanation:
Equation of quadratic function whose vertex is (h, k),
f(x) = a(x - h)² + k
Equation of the function with vertex (-4, -2) shown in the graph will be,
f(x) = a(x + 4)² - 2
This graph is passing through a point (-6, 6) also,
6 = a(-6 + 4)² - 2
6 + 2 = a(-2)²
a =
= 2
Therefore, quadratic function is f(x) = 2(x + 4)² - 2
