Answer:
slope: -1/6
Step-by-step explanation:
to find the slope of a line we can use the formula (y2-y1)/(x2-x1)
this means ththe second y subtracted by the first year divided by the second x subtracted by the first x
when plugged in you get (10-8)/(-7-5)
when simplified it becomes 2/-12 and then -1/6
Wheres the rest of the question, or is that it?
Answer:
a. 86-degrees; angle-2 corresponds to the given angle.
Step-by-step explanation:
Angle 2 is 86 degrees. Whenever a line is bisected by another line, 4 angles are formed. The opposite angles aka the kissing V's have the same angle measurement. Angle 2 and 86-degrees are the kissing V's here, thus they have the same angle measure.
Answer:

Step-by-step explanation:

We use the law of Cosines to be able to find : 1. The measure of the
third side, when the measure of two sides and the included angle of a
triangle ABC are known. 2. The measure of any angle, when the measure of
the three sides of a triangle ABC are known.
The Law of Cosines is c² = a² + b² - 2abcosΘ. It has four variables;
a, b, c and Θ. Whenever you have a triangle with three of these
variables known, use the Law of Cosines to calculate the unknown
variable.
