2a^2+4a+1 is equivalent to 4a+4/2a*a^2/a+1
Since angles 3 and 4 are supplementary, they add up to 180 degrees.
Angle 3 is 88 degrees.
To get the measure of the last angle, let's subtract 88 from 180.
180 - 88 = 92
Thus, Angle 4 has a measure of 92 degrees.
Have an awesome day! :)
Step-by-step explanation:
first u find the angles and then u use some low divide the length of triangle by sin of opposite angles
You know when it is a periodic function if the values repeats in regular intervals or periods. An example of this is trigonometric functions that repeat over intervals of 2 pi radians.
Answer:
9
Step-by-step explanation:
To find the slope of a line, calculate the distance between points with a ratio of vertical to horizontal distance. This is done using the formula:

Here the points are (-7,-2) and (-6,7). Substitute and simplify.
