I need help please !!

41

Step-by-step explanation:

Complementary angles add to 90 degrees

8x+1   + 6x+5   = 90

Combine like terms

14x +6 = 90

Subtract 6 from each side

14x+6-6 = 90-6

14x = 84

14x/14 = 84/14

x =6

We want to find DBC = 6x+5

                                    = 6(6) +5 = 36+5 = 41

konichiwa~! my name is zalgo and i am here to answer your anime-related question today. more than likely, kirishima would kill izuku, marry mino and kiss momo. all of this would be my opinion by the way. (and i am also a weeb lol)

i hope this you! : d

(and do you think you can mark me as brainliest? i'd greatly appreciate it! arigato~! )

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
