I know the answer to the question. It’s just whenever I answer the reason for my answer it gets no marks. Can someone explain how I’m suppose to answer this question? This is a 3 mark question.

x = 60°

Step-by-step explanation:

The triangle has 3 congruent sides and is equilateral with 3 congruent angles each of 60°

x and the base angle of the triangle are alternate angles and are congruent, so

x = 60°

x = 60°

Step-by-step explanation:

Know that the opposite interior angles of parallel lines have equal measurements. In other words, angle x is equal to the bottom-left angle of the triangle. And note that the triangle has 3 sides of the same length, so all 3 angles have the same measurement (i.e. this is a regular triangle). Since the measure of a single interior angle of a regular triangle is 60°, x is also 60°.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
