Step-by-step explanation:
Area=(a+b)/2 x h
a=6x+3
b=4x-5
h=-5x+10
Area= -25x^2+55x-10
Cosine = adjacent / hypotenuse
cos (49)= x/27
27 * cos(49) = x
27 * 0.656 = x
x = 17.7
Answer:

Step-by-step explanation:
pls mark brainliest!
steps:
(23+1/2) + (15+1/8) - (9+3/4) then solve
46+1 over 2 + 120+1 over 8 - 36+3 over 4
solve
47/2 + 121/8 - 39/4
solve
188+121-78 over 8 = 231/8
convert 231/8= 28 7/8
