The place where two equations intersect, has a certain value of y. This means that in the intersection point, the y-values of both expressions are the same, so y = y. Since y is also represented by the following equations, y = 4x and y = 2x - 2, the x-value of the intersection point is 4x = 2x - 2.
(x-center)^2+(y-center)^2=r^2
x^2+y^2=r^2
(7)^2+(0)^2=r^2
49+0=r^2
r^2=49, r=7
x^2+y^2=49
isosceles triangle has its 2 side equals and thus 2 angles opposite to equal side are equal.
consider in a triangle ABC
AB = AC then Angle B = Angle C
so here given angle B = 36
so angle C = 36
now in a triangle sum of all 3 angles is 180
so
angle A + angle B +angle C = 180
angle A + 36 +36 = 180
angle A = 180 - 72 = 108
2)
in a right angle triangle one angle is 90. another one is given as 28
so we kNow sum of all 3 angles is 180
so
third angle + 90 + 28 = 180
third angle = 180 - 118 = 62
Answer:
B
Step-by-step explanation:
.4 as we know can also be handled as .40, as the zero helps us determine the difference in value. 50%, though it is a percentage, can be put into decimal form. That would be .5, or again, we could add a zero to help us out, which would make it .50. As of right now, .4 is less than 50%. 3 and 13 are whole numbers, so they do not really need deep observation, except that 3 is less than 13. That would make the order of number from least to greatest .4, 50%, 3, and 13.
