4y=7x
The sum of the numbers is 22
so, x+y=22
x=(22-y)
by substitute (22-y) for x in the first equation.
Answer:
x ≈ 61.8
Step-by-step explanation:
Using the sine ratio in the right triangle
sin15° = 
= 
( multiply both sides by x )
x × sin15° = 16 ( divide both sides by sin15° )
x = 
≈ 61.8 ( to the nearest tenth )
Answer:
18.84
Step-by-step explanation:
Diameter = 12
Circumference of a circle = πD
= 3.14* 12
=37.68
Since its a semicircle, (that's half of a circle), divide the result by 2
= 37.68/2
= 18.84

Answer:
- GX = 122°
- XU = 148°
- UG = 90°
Step-by-step explanation:
Each arc has the same measure as its central angle. The sum of all of them is 360°.
angle UOG is marked as a 90° angle, so arc UG is 90°.
angle GOX is marked as 122°, so arc GX is 122°.
angle XOU fills out the rest of 360°, so its measure is 360° -90° -122° = 148°. That means are XU is 148°.
The arc measures are ...
- GX = 122°
- XU = 148°
- UG = 90°
