Answer:
B = 42.7 degrees, C = 102.3 degrees and c = 18.7.
Step-by-step explanation:
We use the Sine Rule:
a / sin A = b / sin B
11 / sin 35 = 13 / sin B
11 sin B = 13 sin 35
sin B = 13 sin 35 / 11 = 0.677863
B = 42.7 degrees.
So C = 180 - 42.7 - 35
= 102.3 degrees.
c / sin 102.3 = 11 / sin 35
c = 11 sin 102.3 / sin 35
= 18.7.

The value of π is the ratio of the circumference of any circle to it's diameter, irrespective of it's size.
Answer:
I think it is 9
Step-by-step explanation:
3×3 is 9 + 15= 24÷4=3×3=9
7/10 times x equals 10. x = 10/7. Now you have to multiply 2/5 by 10/7 as well, which equals 4/7, so he can mow 4/7 of an acre per hour
