Solve the variables. See the photo below.

Step-by-step explanation:

1) in the triangle with the angles 45; 90 and 45°: x=4√2/√2=4;

2) in the triangle with the angles 60; 90 and 30°: y=x/sin60°= 4/(√3/2)=8/√3

x = 32 y=

Step-by-step explanation:

solving for x

take 45 degree as reference angle

using sin rule

sin 45 = opposite / hypotenuse

do cross multiplication

root 2 and root 2 gets cancel.Then ,

x = 4

solving for y

take 60 degree as reference angle

using sin rule

sin 60 = opposite / hypotenuse

just now we found the value of x i.e 4 now substitute the value of x here.

do cross multiplication

180

step-by-step explanation:

12-2=10

20-2=18

18x10=180

answer: it is 1: 47 pm
