Answer:
radius is half of the diameter
42/2= 21
the radius is 21 cm
Step-by-step explanation:
Answer:
y=mx+b? That's the equation in slope-intercept form. M= slope B= y-intercept.
1st angle = 3x
2nd angle = x
3rd angle = 65 +x
3x + x +65+x = 180
5x+65 = 180
5x=115
x = 115/5 = 23
2nd angle = 23 degrees
1st angle = 23 x 3 = 69 degrees
3rd angle = 65 +23 = 88 degrees
