Answer:
z=7 and x=60
Step-by-step explanation:
well from the square that is combining the angles 1 and 2, they tell you that that is a right angle and you know that angle 2 is 38 so 90-38=52 which is the measurement of angle 1 so to find z, you would have to divide 38/-2 which is -19 and then add 12 so 12-19=-7 so z=7. so you know that one side =90 degrees so angle 3 must also =90 degrees because they are on the same line and a line is equal to 180, so all you have to do is reverse the operations in 1 1/2x to find x, so 1 1/2 or 3/2 divided by 90 is 60.
pls this took a lot of work and i kindly ask for brainliest.
To work out the average speed you would have to use the formula
AS = 15.0 ÷ 30.0 = 0.5 which is distance divided by time.
The you would do 0.5 x 60 = 30 (60 minutes = 1 hour)
So the average speed would be 30.0 km/h.
15x + 4 would be the algebraic expression
