we find that the slope is (0-3)/(-8-0) so it is -3/-8=3/8 and we have 3/8*2=3/4 so it is (3/4,5) and t=3/4

so we have  3+4+7=14 for all the ratios of the angles then we do 180/14=90/7 for each unit of the ration then we have 90/7*3,90/7*4,90/7*7 for the angles so the angles are 270/7^o,360/7^o,90^o

We are given two angles in each triangle. We can solve for the missing angles. In the upright triangle, the missing angle is 180-50-60=180-110=70. In the upside down one, the missing angle, x, is 180-50-70=180-120=60. Notice than 70 degrees, x, and y form a straight line which is 180. Then y is 180-70-60=180-130=50.

\(\large{-4p+(-2)+2p+3}−4p+(−2)+2p+3\\ =-4p-2+2p+3-4p-2+2p+3\\ =-2p-2p+1+1\\ =-4p+2\)

The area of the shaded area is the large rectangle minus the small rectangle. So we have

(3x+8)(2x+6)-(x+6)(x-3)

=6x^2+34x+48-(x^2+3x-18)

=5x^2+31x+66

Let x be a unit. Then we form an equation for the sum of the triangle's angles:

3x+4x+7x=180

18x=180

x=10

Then 3x=30, 4x=40, and 7x=70.

9 since 3^2=3*3=9 so a=9

LOL so funny

Excellent work!!! 

But what's an elaborate number?

Translated:

Why 1 is not considered an elaborate number? After all, its only divisor is 1, and the sum is 1

Good job, heureka!!!

oops I divided but it was supposed to be multiplied thanks Guest

I do just find the post and type in what you want to say and press enter

First find the slope using the two points, then find the equation, then plug in the value 5 as y to get t!
