Answer:
52 m
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 + 39^2 = 65^2
a^2 + 1521 = 4225
4225 - 1521 = 2704
Square root of 2704 = 52
Answer:
Step-by-step explanation:
A is correct. csc x = 1/ sin x
B is correct. y = sin x is a continuous funtion, for all real numbers, x
C is correct. The function y = sin x is a periodic function, and the cycle repeats every 2 radians (or 360°).
D is incorrect. It doesn't actually say anything false, but it does not accurately describe the behavior of the sine function. Look at the graphic I have attached. If you start at the origin, you see y = 0, then increases to 1 when x = π/2, <u>then decreases back to zero when x = π,</u> then decreases even more to -1 when x = 3π/2, then increases back up to zero when x = 2π.
Answer D leaves out the underlined part.
Hope this helps.
I think its the second one
Answer:
Similar AA
Step-by-step explanation:
To find the third angle of a right triangle you add 90 to the angle and subtract from 180
so angle E is 180-(55+90)=35 so the triangles have 2 angles are the same so
