Let the smaller angle = x
Larger angle = x + 10
They add up to 180
x + x + 10 = 180
2x + 10 = 180
2x = 170
x = 85
x = 85
x + 10 = 95
Answer: The angles are 85° and 95°
To find the scale factor of the dilation, divide the new point's x and y values by the original point's x and y values:
The scale factor of the dilation is
0.75.
Answer: For 1 it is A - f(x)=(x-2)(x+4) and for 2 it is C - y = 0.5x^2 + 1.5x − 5
Step-by-step explanation:
Just use Desmos
To check, we can solve how much sunscreen is in a family sized bottle first. We need to find what is 20% of 12. First, turn 20% into a decimal: 20%/100= 0.2. Now, multiply 0.2 by 12, which is 2.4. Then, you add this to 12 because it is 20% more. 12+2.4= 14.4. Multiply this by 4: 14.4*4=57.6. Since his number is close to 50, he is kinda correct, but a much more reasonable answer would be closer to 60. Hope this helped!
Answer:
A. 60°
Step-by-step explanation:
3tan^3 x= tan x
3tan^2x = 1
tan^2 x = 1/3
tan x = 1/
x = 60°
