Answer:

The average speed would be 10.1 kilometers per hour.

Step-by-step explanation:

If we convert both times into minutes, it will make solving this much easier. After finding the speed for both legs, we can find the average by adding the two values together and dividing by 2. This results in 10.11430568 or can be rounded to 10.1.

Help pls dont give just the answer pls step by step so i can understand

Irina-Kira [14]

Answer:

y=14

Step-by-step explanation:

Since this is an isosceles triangle due to opposite sides being congruent, the base angles would also be congruent.

$50 = 2x \\x=25$

plug in 25 in 2x and you would get 50°

Since the sum of a triangle is 180° you could set up an equation $50+50+5y+10=180$

Then, add 50+50=100+10=110

then you would then have $5y+110=180\\$

subtract 110 from 180, leaving you with 70

$5y=70$

then divide and you would get 14

Check:

5(14)+10+50+50= 180
