In the right triangle shown angle Q is equal to 60 in QR is equal to two radical three how long is PQ

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

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
