Given bold u equals negative bold i plus bold j, bold v equals 10 bold i minus 2 bold j, and bold w equals negative 8 bold j, find proj bold subscript u left parenthesis bold v plus bold w right parenthesis. given u=-i+j, v=10i-2j, and w =-8jfind proj subscript u (v+w)

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
