Answer:
what is the equation and what do we solve for?
Step-by-step explanation:
what we solve for?
Answer:
Option C
Step-by-step explanation:
Area of a triangle given with measures of 2 sides and angle between these sides will be,
Area of a triangle = 
Here, a and b are two sides of the triangle and C is the angle between these sides.
From the figure attached,
a = 6, b = 9 and m∠C = 110°
Substitute these values in the formula,
Area of ΔQRS = 
= 
= 25.37
≈ 25.4 square units
Therefore, Option C will be the answer.
Step-by-step explanation:
is there any value for S??
Answer:
8
Step-by-step explanation:
The formula to calculate the sum of interior angles of polygon is (n - 2)180
Where n represents number of sides
(n-2)180 = 1080 ------ Divide through by 180
(n-2)180/180 = 1080/180
n-2 = 6
n = 6+2
n = 8
