Answer:
Step-by-step explanation:
Before giving the exterior angles, find the third angle. A triangle (all triangles) measure 180 degrees.
35 + 80 + x = 180
115 + x = 180
x = 180 - 115
x = 65
Exterior angles are supplements of the interior angles.
So the exterior angle to 65 degrees is 180 - 65 = 115
And the exterior angle to 35 degrees is 180-35 = 145
The exterior angle to 80 degrees is 180 - 100 = 80
You would find the are of the triangle (base x height) and subtract it from the area of the circle(pi x diameter)

Answer:
7/12
Step-by-step explanation:
To find the probability of drawing a blue marble you need to find how many marbles there are in total.
So you have to add 3 red marbles, 7 blue marbles, and 2 green marbles to get the total.
So 3 + 7 + 2 = 12
There are 12 marbles in total so now you have to find how many blue marbles there are.
There are 7 blue marbles out of 12 marbles.
Now you have to put this as a fraction to see if it can be simplified.
7/12 cant be simplified, so the probability of drawing a blue marble is 7/12.
Can you maybe take another screenshot I can’t see what it says.
