Answer: 135°
Step-by-step explanation:
The sum of the angles in a pentagon is equal to 540°, and the sum of the first four angles is 405°.
70 + 90 + 100 + 145 = 405
540 - 405 = 135
Answer:
59˚
Step-by-step explanation:
The sum of all the angles in a triangle is always 180 so:
38 + 83 + x = 180
121 + x = 180
x = 59
Slope is negative for each...Remember Y-int and rise/run for slope.
Y=mx+b
Y= -2/3X - 2
Y= -5/2x + 2
The answer for this question is 1468
