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.
Answer:
(2,-1/2)
Step-by-step explanation:
(9+(-5))/2= 2
(6+(-7))/2= -1/2
Answer:
1/8 because you do 5 divided by 5 and 40 divided by 5 which gives you 8. Meaning, 1/8 is the answer.

Step-by-step explanation:
Given:
Required:
Find the missing numbers of each unit rate.
SOLUTION:
All you need to do to find the missing number of each unit rate is just to divide.
Thus:
✍️ (16 ÷ 4 = 4)
This means 4 quantities of the numerator per 1 quantity of the denominator.
✍️ (60 ÷ 5 = 12)
This means 12 quantities of the numerator per 1 quantity of the denominator.
Check the picture below.
you can do a search for the "inscribed quadrilateral conjecture", the proof is rather simple.
now, we know "x" cannot be a negative value, because that makes ∡C a negative angle, which is not feasible for this case.
we know ∡B = 7x - 10, and we also know what "x" is, thus
