if you mean the triangle one, it's 25cm
Answer:
Diameter, D = 2.65 cm
Step-by-step explanation:
<u>Given the following data;</u>
Circumference of circle = 8.34 cm
To find the length of its diameter;
Mathematically, circumference of a circle is equal to;
C = πD
Where;
- C is the circumference of a circle.
- D is the diameter of a circle.
- Pie, π = 3.142
Substituting into the formula, we have;
8.34 = 3.142 * D

<em>Diameter, D = 2.65 cm</em>
A) a is complementary to 70° so it is 20°
b) a and b are complementary so b is 70°
c) c is complementary to b so it is 20°
d) d is complementary top c so it is 70°
e) e is a linear pair with d so it is 110°
3) supplements add to 180 so 180-122=56
4) p and q are supplementary so q=180-90=90
5) a and t are complementary sup both are less than 90. that means the supplement out both is >90 and thus obtuse
6) acute
28 x 12 = 336
336 - 16 = 320
320 divided by 4 = 80
80
