Answer:

A.105°

Step-by-step explanation:

Angle at W and V are equal and the angles at T and U are also equal

Hence taking angles at T and U...so as to calculate the value of x

5x + 15 = 3x + 21

5x - 3x = 21 - 15

2x = 6.....hence, x = 3

Then for the angle of VXU;

All angles in a triangle add up to 180°

15(3) + 3(3) + 21 = 75°...then subtract from 180°..so as to obtain angle at VXU

180 - 75 = 105°

A circle has a circumference of 907.46.<br> What is the diameter of the circle?

Anna007 [38]

$\bf \textit{circumference of a circle}\\\\ C=\pi d~~ \begin{cases} d=diameter\\[-0.5em] \hrulefill\\ C=907.46 \end{cases}\implies 907.46=\pi d\implies \cfrac{907.46}{\pi }=d \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill 288.85\approx d~\hfill$

Savatey [412]

Answer:

The + 78 :- it should be + 60.

Step-by-step explanation:

Long division:-

x - 3 )4x^4 - 6x^3 + 0x^2 + 6x + 3 ( 4x^3 + 6x^2 + 18x + 60 <--- Quotient.

4x^4 - 12x^3

6x^3 + 0x^2

6x^2 - 18x^2

18x^2 + 6x

18x^2 - 54x

60x + 3

60x - 180
