Answer:
8x + (6x + 6) = 90°
x = 6°
Step-by-step explanation:
because it is a right angle, the sum of the angles = 90°
8x + (6x + 6°) = 90°
simplify:
14x + 6° = 90°
subtract 6° from each side:
14x = 84°
divide both sides by 14:
x = 6°
Answer:
x=-6

Answer:
Step-by-step explanation:
Scale= length on drawing / actual length
Let the actual length b x
3:10=2/5/x
3/10=2/5x
Cross multiply
15x=20
x=4/3
The actual length is 4/3
Step-by-step explanation:
by having two equations that have the same point, you can set the two equations equal to each other
y = 12x + 3, y = x + 1
12x + 3 = x + 1
11x = -2
x = -2/11
when you find the the x value, plug it back into either one of the equations
y = x + 1
y = (-2/11) + 1
y = 11/11 - 2/11
y = 9/11
the point (solution):
(-2/11, 9/11)
