Answer:
D
Step-by-step explanation:
Angles outside a circle are half the difference of the measures of the intercepted arcs.
78 - 12 = 66
66/2 = 33
The angle is 33 degrees
It’s 12.6, the top and bottom sides are parallel to each other.
Printer $309 Computer $927
p+3p=1,236
4p=1,236
p=309
309x3=927
309+927=1,236
Double the number like 2 x5 would be 5+5
Lets see!
We need to use the pythagorean theorem (a^2+b^2=c^2) to check.
So..
15^2+ 17^2 = 19^2
225+ 289= 361
Hm 225 and 289 do NOT equal 361 therefore it is NOT a right triangle.
