The measurement of D can be anyone one of these but where's the rest of the problem like a pic or the measurements of any other angles?
X=15
3x+7+10x-22=180
13x-15=180
13x=195
X=15
Step-by-step explanation:
Determine whether the triangles are similar by AA~, SSS~, SAS~, or not similar.
Answer:
r = 16.5
Step-by-step explanation:
Move the subtraction over to the over side first
0.1r - 1 = 0.65
It becomes addition on the right side
0.1r = 0.65 + 1
Move the multiplication over to the over side first
0.1r = 1.65
It becomes division on the right side
r = 1.65 / 0.1
r = 16.5

Answer:
9.2 cm
Step-by-step explanation:
The arc length is given by ...
s = rθ . . . . . where r is the radius, and θ is the central angle in radians
Here, we have ...
s = (7.9 cm)(66.4/180π) = 7.9·66.4·3.14/180 cm ≈ 9.2 cm
Arc length CD is about 9.2 cm.
