Answer:
77.2°
Step-by-step explanation:
Consider the triangle JKR.
∠KJR=108.6 (lies on the same line as ∠RJA, angles on a straight line add up to 180)
All the angles in a triangle add up to 180, so:
∠JKR+∠KJR+∠JRK=180
∠JKR+108.6+32.8=180
∠JKR=38.6=∠RKA
Consider ∠RKA. This angle stands on the same arc as ∠RCA.
Since the angle at centre is twice the angle at circumference, 2(∠RKA) = ∠RCA.
2(∠RKA) = ∠RCA
2(38.6)=∠RCA
∠RCA=77.2°

Step-by-step explanation:
its B
Answer:
28 Square units
Step-by-step explanation:
Here, numbers are: 1.4 and 1 4/5 = 9//5 = 1.8
Now, you need to know, which number is between 1.4 and 1.8
1.34 is lower than 1.4 So, it can't
170% = 170/100 = 1.7
So, 170% is that number between 1.4 and 1 4/5
Hope this helps!
