U need the law of cosines and heron's formula
Answer:
y = 1 and x = - 6
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c ( where c is the value of the y- coordinates the line passes through )
The line passes through (- 6, 1 ) with y- coordinate 1 , then
y = 1 ← equation of horizontal line
The equation of a vertical line parallel to the y- axis is
x = c ( where c is the value of the x- coordinates the line passes through )
The line passes through (- 6, 1 ) with x- coordinate - 6 , then
x = - 6 ← is equation of vertical line
Question 2: The answer is A. 90, 45, 45 because one angle is a right angle which is always 90 degrees and the two remaining angles are the same. Also, all triangles have to have a total amount of 180 degrees when all angle-degree-measurements are combined, which leaves A as the only possible answer.
Question 3: The answer is D. To solve this question you simply multiply all the dimensions of the triangular prism together. That would be: 10 x 14 x 8 = 1,120 in squared
Question 4: Sorry, didn't get this one :(
Question 5: The answer is B. 4pi. Sorry, don't have a good explanation for this one, but I'm pretty sure it is correct.
Question 6: Can't see the question, so I can't help you :(
Question 7: The answer is A. 5 feet. Using the power of elimination you can conclude that the three other options to the answer are improbable.
Question 8: The answer is B. 180 - x. To get this you need to know that 180 degrees is a flat line angle. Since angle x and angle y stem from the same two flat lines intersecting diagonally, you can determine the 180 - angle x would equal angle y.
Answer: 105
