The answer is a d there both irrational
Answer:
D.51.34°
Step-by-step explanation:
tan(angle wvx)=WX/WV
i.e,tan(angle wvx)=5/4=1.25
i.e,angle wvx=tan⁻¹(1.25)
=51.34°
Answer:
Yes for 1st and 4th, No for the 2nd, 3rd and 5th.
Step-by-step explanation:
You need to plug the first number in each set of brackets into x and the second number into y. The first equation asks if y is the greater than -x. The only ones this is true for are the 1st, 3rd, and 4th answers, so the 2nd and 5th are no. Now check the 1st, 3rd and 4th to see if the answer is less than or equal to 2 when plugging in x and y. This is true for the 1st and 4th answers, so move those to yes and the 3rd to no.
Answer: Yes for 1st and 4th, No for the 2nd, 3rd and 5th.
Consider the converses:
a) If two planes have no points in common, then they are parallel. (true)
b) If a point lies on the y-axis, then it has x-coordinate 0. (true)
c) If two angles have the same measure, then they are congruent. (true)
d) If a figure has four sides, then it is a square. (FALSE) (A figure with 4 sides may not even be a plane figure.)
