Answer:
slope of 1/4
Step-by-step explanation:
slope formula= y2-y1/x2-x1
coordinates i chose: (0,60) (40,70)
70-60/40-0=10/40=1/4
therefore slope of 1/4
hope this helps, also what grade is this problem
It already is a decimal:)
The angle measure of a straight line is 180°, and so if the you know that one angle off of it is (5x)°, then you know that the other section is (180 - 5x)°.
Because it's an isosceles triangle, there are two identical angles, which happen to be the angles with the measure of (5x - 30)° and (180 - 5x)°.
Since they have the same measure, 5x - 30 = 180 - 5x. Solve:
Thus,
x = 21°.
The area of one face of the cube is 144cm2
