Answer:
Step-by-step explanation:
we know that
The measurement of the external angle is the semi-difference of the arcs which comprises
In this problem
m∠RPS=
------> external angle
so
m∠RPS=
we have
m∠RPS=
substitute the values
Solve for arc RS
The correct answers are as follows:
11) 110 - alternate exterior angles
12) 84 - alternate interior angles
13) 80 - supplementary angles
14) 111 - alternate interior angles
15) 125 - alternate interior angles
16) 47 - alternate exterior angles
17) 53- corresponding angles
18) 113-alternate interior angles
Hope this answers the question.
Answer:
24
Step-by-step explanation:
We know that
Area of a circumference=π*r²
for diameter=21.2 cm---------> r=10.6 cm
A=π*10.6²--------> A=π*112.36 -------> A=352.81 cm²
if 2π radians (full circumference) has an area of -----------------> 352.81 cm²
<span>3π/5 radians-------------------------------------> X
X=[(</span>3π/5)*(352.81)]/2π---------> X=105.84 cm²
the answer is 105.84 cm²
