The relationship is proportional because it is in standard form
Answer:b
Step-by-step explanation:
The awnser is 148 You just need to add the two to get the original price
Answer:
x=-10
Step-by-step explanation:
since there's a given 120 degrees, and it's a isosceles triangle, we know that the line adds up to 180 (where the 120 degrees is). so 120+x=180, the interior angle measures 60 degrees. That being said, the 3 angles measure 60 degrees also. now there's a right angle mark on top, so we find the angle of the smaller triangle (near angle 2) by doing 90-60=30 degrees.
angle 2 is said to be x+160, and there's a line, which tells us that they must add to 180.. so x+160+30=180
x+190=180
x=-10.
As you want to find angle A
Just get to know one thing that
The two given lengths 6,8 are opposite side and adjacent side
so angle A can be get by tan(A)
so Angle A = tan-1(6/8)
