so i think its 
at the bottom: 6 x 7 = 42
sides: 5 x 7 x 2 = 70
triangles : 2 x 1 / 2 x 6 x 4 = 24
42+70+24 equals to 136!! hope u understand ^^
15% of 80 is 12, so he got $12 in tips

Answer:
θ = 50 degrees
Step-by-step explanation:
we have sin θ = cos 40°
θ = arcsin ( cos 40°)
and make sure θ is less than 90 and greater than 0
θ = arcsin (0.766044443)
θ = 50 degrees
<span>(3x-4)+(x+3)^2
= 3x - 4 + x^2 + 6x + 9 .........(expand using (a+b)^2 = a^2 + 2ab + b^2)
= x^2 + 9x + 5 ..........(combine like terms and simplify)
hope that helps</span>
