Answer:
Center:-1,-2
Radius: 2
Step-by-step explanation:
Ok, get the form of a circle from this equation-
(x+2)^2+(y+2)^2=4
Since this is the form of a circle, I can figure out the center and the radius from here,
r=2
h=-1
k=-2
Center:-1,-2
Radius: 2
Answer:
m<DCA = 40
Step-by-step explanation:
m<DAC = 90
m<CDA = 50
m<DCA = 180 - 90 - 50 = 40
Answer:
x + 20° = 35.56°
3x + 10° = 56.68°
5x + 10° = 87.8°
Step-by-step explanation:
Assume;
Given measures are angle of a triangle
x + 20°
3x + 10°
5x + 10°
Find:
Value of each angle
Computation:
We know that, sum of all interior angle in a triangle is 180°
So,
We say that
x + 20° + 3x + 10° + 5x + 10° = 180°
9x + 40° = 180°
9x = 140°
x = 15.56°
So,
x + 20° = 15.56 + 20 = 35.56°
3x + 10° = 3(15.56) + 10 = 56.68°
5x + 10° = 5(15.56) + 10 = 87.8°
2/3 ÷ 4 = 2/3 * 1/4 = 2/12 = 1/6
