Answer:
x=27
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
90 + x+15 + 2x-6 = 180
Combine like terms
3x+99=180
Subtract 99 from each side
3x+99-99=180-99
3x =81
Divide each side by 3
3x/3 = 81/3
x=27
Answer:
Step-by-step explanation:
Triangle ABC has vertices at A(3, 8) , B(11, 8) , and C(9, 12) . Triangle FGH has vertices at F(1, 3) , G(9, 3) , and H(7, 7) .

Hmm, (x,y)
x is horizontal or left right
y is vertical or up down
so
we see that A to F is move left 2 and down 5
B to G is left 2 and down 5
C to H is left 2 and down 5
so translatete ABC left 2 and down 5 and
translate FGH right 2 and up 5
not 1st option
2nd works
3rd works
4th is false
2nd and 3rd
Answer: (-2, -5)
Explanation:
The solution to the system is where the lines intersect. The point (-2,-5) is on both the blue and orange line simultaneously.
The point (-2, -5) means x = -2 and y = -5 pair up together to form the full solution.
You know that the sum of all angle is 180 and in right angle triangle one of the the angle is 90 so you have 75 and 90 which the sum of them is 165 so the third angle is 15
