What is the value of x

x= 98°

Step-by-step explanation:

Concept:

Here, we need to know the concept of the "Exterior Angle theorem"

The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two opposite angles of the triangle.

If you are still confused, you may refer to the attachment below for a graphical explanation.

Solve:

x = 53 + 45 = 98°

Hope this helps!! :)

Please let me know if you have any questions

The value of x = 98°

Step-by-step explanation:

=> angle FGH +53+45=180

=> angle FGH = 180-98

=> angle FGH = 82

now ,

=> angle FGH + angle x = 180

=> 82 +angle x = 180

=> angle x = 180-82

=> angle x = 98

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
