X=2 . HOPE THIS HELPED !!!!
X= 5y + 1
-2x + 9y = -1
-2(5y + 1) + 9y = -1
-10y - 2 + 9y = -1
-y - 2 = -1
-y = 1
y = -1
x + 5 = 1
x = -4
(-4, -1)
The value of x is 5. Angle one and four are vertical. You can do this by writing 7x = 3x + 20. Isolate the variable by moving 3x to the other side. If you do this, 3x becomes negative, and you end up with 7x-3x = 20 --> 4x = 20.
x=5.
Answer:
I only know the answer to part A. The triangles ARE similar and they ARE congruent.
Step-by-step explanation:
The big triangle has 75° and 60°.
The little triangle has 75° and 45°
75°+60°+45° = 180°
45° is the missing interior angle for the big triangle.
75°+45°+60° = 180°
60° is the missing interior angle for the little triangle.
Answer:
6209.07
Step-by-step explanation:
A = P(1+R/100)^t
where P = 5200 R= 3 and t =6
I = A- P
