What’s the answer to this?!!

65*65-39*39 is the answer

52

Step-by-step explanation:

Using the reverse Pythagorean Theorem we can get the answer quite easily. If  A^2 + B^2 = C^2, then by that same logic, C^2 - A^2 = B^2. That means 62^2, or 3844, minus 39^2, or 1521, equals 2323. The square root of that is 52.

Hope that this helps!

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
