The sum of the angles in a triangle is always 180°.
49 + R + 80 = 180
180-129=51
Now,
We know that line PX = 180° because it’s a straight line
51 +
180+51 = 129
a) is correct
So,
123/20 is over 1. The denominator is 20, so what I would do is find out how many <em>whole </em>20's would fit in 123.
The result is that 6 20's would fit in 123 with 3 left over.
The answer is six and three-twentieths (6 3/20). It's already in simplest form.
Answer:
1 is 69 degrees. 2 is 111 degrees
Step-by-step explanation:
1 is 69 because when a line intersects with 2 paralell lines, 1 and the 69 degree angle are the same degree. we know that the second angle plus 69 degrees is 180, so 180-69 is 111.
Answer:
the answer is below
Step-by-step explanation:
We must find the equation in order to make the graph.
According to the statement, the equation would be:
E = v * t - Ei
Being Ei (20) the initial elevation, t the elapsed time and the speed that is 4, we replace and we are left with:
E = 4 * t - 20
Now, we must calculate the corresponding values:
E (0) = 4 * 0 - 20 = -20
E (1) = 4 * 1 - 20 = -16
E (2) = 4 * 2 - 20 = -12
E (3) = 4 * 3 - 20 = -8
E (4) = 4 * 4 - 20 = -4
E (5) = 4 * 5 - 20 = 0
If we graph we would have the attached image:
Answer:
The potato salad costs 4.63
Step-by-step explanation:
We have 1.75lb
1=2.75
then 75% of 2.75 is 2.0625
the answer is 4.63
