What is the measure of angle A?

I am Lyosha [343]

First you have to find the angle B (check attachment)

$B = 180^{\circ} - 137^{\circ} = 43^{\circ}\\$

Then you can find the last angle inside the triangle, which I'll call C

$C = 180^{\circ} - 102^{\circ} - 43^{\circ} = 35^{\circ}$

Now you can find angle A

$A = 180^{\circ} - C = 180^{\circ} - 35^{\circ} = 145^{\circ}$

The sum of three consecutive odd integers is 297. Compute the PRODUCT of the same three consecutive odd integers.

svetoff [14.1K]

Answer:

Step-by-step explanation:

let the odd numbers be x,x+2,x+4

x+x+2+x+4=297

3x+6=297

3x=297-6=291

x=291/3=97

consecutive odd integers are 97,99,101

97×99×101=97×(100-1)×(100+1)=97×(100²-1)=97×100²-97=970000-97=969903
