What is the length of AB?

Tresset [83]

Answer:

angle B'CA'= angle BCA..... (common angle)

angle B'A'C = angle BAC.....(corresponding angels)

therefore,

ΔCB'A' ~ ΔCBA. ......(by A-A test of similarity)

therefore,

B'A'/ BA. = CA'/ CA....(congruent sides of congruent triangles)

now, B'A' = 5, CA'= 6 , CA = 6 + 3 = 9

5 / BA. = 6 / 9

therefore, 5 / BA. = 2 / 3

$ba \: = \frac{5 \times 3}{2 } \\ = \frac{15}{2} \\ = 7.5$

Answer : AB = 7.5 units

Which of the following sums would be under the radical symbol to find the distance between the points (7, -1) and (-8, -9)?

Alex

So the distance formula is $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ . Using this, our equation is $\sqrt{(7-(-8))^2+(-1-(-9))^2}$ and we can solve for it as such:

$\sqrt{(7-(-8))^2+(-1-(-9))^2}\\ \sqrt{15^2+8^2}$

As we see with this radical, the sum that's under it is 15^2 + 8^2, or the third option.
