Blaize has to take four tests in his physics class. He did not prepare for the first test and scored a 65. The average of the four tests must be a 80 or more in order for him to pass his class. What is the lowest possible average Blaize could earn on the next three tests to receive an 80 the class. Select one:

ege

step-by-step explanation:

egge

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
