Answer:
14.5 =x
Step-by-step explanation:
Since this is a right triangle we can use trig functions
sin theta = opposite side/ hypotenuse
sin A = BC / AB
sin 65 = x /16
Multiply each side by 16
16 sin 65 =x
14.50092459 =x
14.5 =x
Answer:
25 degrees
Step-by-step explanation:
The sum of the 80 and 55 degree angles and the unknown angle x must be 180 degrees. Thus, x + 80 + 55 = 180, or x + 155 = 180, or x = 25.
x is 25 degrees.
This is based upon the "corresponding angles" principle. Lines AB and CD are parallel and are intersected by the longer diagonal line if we extend this line past the 80 and 55 degree angles.
if the point (9,26) lies on the graph y=f(x) then y=
{inverse function} must contain (26,9)
The inverse of function:
A function that can reverse into another function is known as an inverse function or anti-function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. The inverse function is denoted by
or
if the function is represented by "f" or "F"
Given (x,y)=(9,26)
i.e.f(x)=y
⇒f(9)=26
inverse means swap x and y
i.e. y= ![f^{-1}(x)](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29)
⇒
= y
⇒
=9
Therefore, y=
must contain (26,9).

Answer:
E=5(m+c)
Step-by-step explanation:
Since Bryan earns $5 for every lawn mowed, the equation right now is 5m. We have to add the $5 for the cars washed, 5c.
- 5m+5c
- That can be factored, 5(m+c)
Answer:
30°
Step-by-step explanation:
Use that
-the sum of angles in a triangle is 180° and that
-vertical angles are congruent ( angle x and the missing angle in the bottom triangle are vertical)
x= 180-75 -75 = 30°
