its B 4.1 in.
We have a point and the slope, so we can use the point-slope formula.
Where m is the slope and (x₁, y₁) is the point the line passes through.
We know the slope of the line is -2 and the point it passes through is (4, 7).
Substitute the values into the formula.
We are asked to write the equation in point-slope form, so this is our final answer.
The equation of the line in point-slope form is: y-7= -2 (x-4)
The lateral area = 450 mm²
The lateral area of any prism is equal to the areas of the sides faces
∵ The base of the prism is triangle
∴ It has 3 side faces
∵ The lengths of the side faces are 5 , 12 , 13 and their height is 15
∴ The lateral area = (5 × 15) + (12 × 15) + (13 × 15)
= 75 + 180 + 195 = 450 mm²
I assume when you say vertical you mean a straight line.
If so, then the answer is NO, two obtuse angles cannot be vertical. Obtuse angles have to be greater than 90 degrees, so the least an obtuse angle can be is 91 degrees.
91 + 91 = 182, and a straight line is 180 degrees.
So two obtuse angles cannot be vertical because even the lowest degrees that two obtuse angles can be is greater than 180 degrees (a straight line).
Anserr what the question?
