Answer:
<R=23°
Step-by-step explanation:
The sum of angles in a triangle is 180°
So, <R + <S + <T = 180°
<R+90°+67°=180°
<R+157°=180°
<R=23°
Answer:
30 Lower level tickets
17 upper level tickets
Step-by-step explanation:
Let:
Lower level tickets = l
Upper level tickets = u
5l + 9u = 303 - - - (1)
8l + 10u = 410 - - - - - (2)
Multiply (1) by 8 and (2) by 5
40l + 72u = 2424 - - - (3)
40l + 50u = 2050 - - - (4)
Subtract (3) from (4)
22u = 374
u = 374 / 22
u = 17
Put u = 17 in (1)
40l + 72(17) = 2424
40l + 1224 = 2424
40l = 2424 - 1224
40l = 1200
l = 1200 / 40
l = 30
30 Lower level tickets
17 upper level tickets

Answer:
121 sq. in
Step-by-step Explanation
area of the frame = 48 square inches
if is the side length of the square, then ( + 2) is the side length of the square after the frame has been added.
the area of the picture + the frame is:
( + 2) ( + 2)
the area of just the frame is given by ( + 2) ( + 2) - x :
( + 2) ( + 2) - x =48
²+ x 2 + 2 x + 2 x 2-² = 48
² + 2 + 2 + 4-² = 48
4 + 4 = 48
then subtract 4 from both sides:
4x = 44
and divide both sides by 4:
x = 11
the area of the square is 11 (11) = 121.
i think this is correct?
hope this helps
