Answer:
a = 10.5 feet
Step-by-step explanation:
Given that,
The area of a square room, A = 110.25 ft²
We need to find the side length of the living room. Let the side be x.
We know that,
The area of a square, 
So,

So, the side length of the living room is equal to 10.5 feet.
[2(x+10)] =
well we have to add first
x=1 + 10= 11 since there is parenthesis around the "11" it is times 11 x 2 = 22
we will just have to times this and put a - in front of the 90 (3x - 30) = -90
Hope I could help out.
sinA+sinB+sinC
=2sin(A+B)/2cos(A-B)/2+sin C
=2sin(pi-C)/2cos(A-B)/2+2sin C/2cosC/2
=2cosC/2(cos(A-B)/2+cos(A+B)/2)
=4 cos A/2 cos B/2 cos C/2
= RHS
Answer:
x=31
Step-by-step explanation:
QPC is a triangle. All angles of a triangle adds up to 180.
(x+11)+(2x+6)+70=180
x+11+2x+6+70=180
Combine like terms
3x+87=180
Subtract 87 from both sides
3x+87-87=180-87
3x=93
Divide both sides by 3
x=31
