Here's the solution ~
As we know, we can calculate the circumference of a circle in terms of its diameter as :

where, c = circumference and d = diameter
And also, circumference of circle is terms of radius (r) is :

step 1
Find the measure of angle 1
REmember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
In the triangle ABC
90+58+<1=180
148+<1=180
<1=180-148
<1=32 degrees
step 2
Find the measure of angle 2
we know that
<2=<1 -----> bt vertical angles
so
<2=32 degrees
step 3
Find the measure of angle 3
REmember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
In the triangle CDE
32+108+<3=180
140+<3=180
<3=180-140
<3=40 degrees
Answer:
Left
50 feet
Right
16 inches
10 inches
Step-by-step explanation:
Here, we want to make a conversion and fill in the empty spaces
The scale is 1 foot is 1/8 inch
To convert from foot to inch, we multiply by 1/8
To convert from inch to foot, we multiply by 8
Thus, we have ;
Let’s fill in the left spaces first;
6.25 * 8 = 50 feet
Right spaces, top to bottom;
128 * 1/8 = 16 inches
80 * 1/8 = 10 inches
Answer:

Step-by-step explanation:
Let the missing integer be x
Solve for x

Move 3 to right hand side and change it's sign

The negative and positive integers are always subtracted but posses the sign of the bigger integer

Change the signs of both sides

Hope I helped!
Best regards! :D
Answer:
C. 72
Step-by-step explanation:
So imagine every straight line you see equals to 180 degrees, so given one side of the angle...180 - 108 = 72
