Answer:
d
Step-by-step explanation:
In this case, we will use our Pythagorean Theorem.
a = 84
b = 13
c = x
Thus,
x = 85.
Answer:
-4
Step-by-step explanation:
The formula for slope is: m=y2-y1/x2-x2
12-(-20)/5-13
Since the measure of angles adds up to 180, you should add all of the known angles up and subtract from 180 to find the missing angle. For example: 47+69=116
and
180-116=64 so the measure of the missing angle is 64 degrees
85+42= 127
180-127=53 s the measure of the missing angle is 53
