Answer:
Step-by-step explanation:
It is an obtuse triangle because one angle (5) takes up more than the sum of the other two (3+1=4).
The angles are:
5+3+1 = 9
Each angles is
5/9 * 180 = 100°
3/9 * 180 = 60°
1/9 * 180 = 20°
Total = 100+60+20 = 180 degrees.
Answer:
third angle = (-6x + 161)°
Step-by-step explanation:
180° = (x)° + (5x + 19)° + third angle →
180° = (6x + 19)° + third angle →
180° – (6x + 19)° = (6x + 19)° + third angle – (6x + 19)° →
180° – (6x + 19)° = third angle →
180° + -(6x + 19)° = third angle →
180° + (-6x)° + (-19)° = third angle
180° – 6x° – 19° = third angle
(180° – 19°) – 6x° = third angle
161° – 6x° = third angle
third angle = 161 – 6x°
third angle = -6x° + 161°
third angle = (-6x + 161)°
Answer: 8 feet
Step-by-step explanation:
Ok so first you turn 2 Yards into feet because the answers are all in feet by multiplying by 3/1 so it would look like this 2/1x3/1 which is 6 then you use proportion to get the 6 yards by it self so it would look like this 48/6 6/6 the you would get x= 8 feet to get 8 feet you dividied 48 by 6 hope this helps
3b^2 - x = -9b^2
x = 3b^2 +9b^2
x = 12b^2
3b^2 -12b^2 = -9b^2
hope this will help you
