Right triangle QRS is pictured below. image d0311b0d418c43c9925bfb6dc95e92ef Which equation gives the correct length of side RS ? A cos31°=24.8RS B cos31°=RS24.8 C sin31°=24.8RS D sin31°=RS24.8

step-by-step explanation:

i think you should think about the question and not look online.

it is not that hard all u have to do is plot the graph

step-by-step explanation:

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
