Supplementary angles add up to 180°, meaning that the supplement of 25° can be added to it to get 180°.
To find the supplement, subtract 25° from 180°.
180° - 25° = 155°
To simplify, we need to use the distributive property.
0.5 * 4a + 0.5 * 6b
2a + 3b
Now we have our final answer: 2a + 3b

X = low-energy lamp
y = high-energy lamp
1) 4x + 5y
2) 120= 4x + 5y
Answer: H = 8 cm
Step-by-step explanation: Since a triangle's area is b times h/2, we know that two times 48 is 96, therefore we can opposite the equation so 12 is the base times the height (8 cm) is 96 divided by 2, there's your answer.
The answer is choice C
Plane D(choice C) because choice a and b are not lines(one letter cannot be a line and PBC and not connected). It's not d because e isn't a point
