Can someone help me pleaseee

x ≈ 26.4

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos47° = = = ( multiply both sides by x )

x × cos47° = 18 ( divide both sides by cos47° )

x = ≈ 26.4 ( to the nearest tenth )

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

there are infinitely many solutions.
