Answer:
∠SQR = 1/2 m ∠SR = 1/2 x 86 = 43°
Answer:
Option A
Step-by-step explanation:
The complete question is shown in the attachment.
The sum of angles in a triangle is 180 degrees.
This implies that:

m<A+138=180
m<A=180-138=42
Now we use the sine rule to find AC=b

This implies that:


Answer:
x=−21
Step-by-step explanation:
Answer:
b
Step-by-step explanation:
subtract 6 from the 21x+6. Then divide by 21. The answer is going to be -6/21
